Not all translations use the word 'molested' many others use words such as 'annoyed' and 'maligned'
Examples:
M.M Pickthall Translation:
O Prophet! Tell thy wives and thy daughters and the women of the believers to draw their cloaks close round them (when they go abroad). That will be better, so that they may be recognised and not annoyed. Allah is ever Forgiving, Merciful.
Dr. Laleh Bakhtiar:
O Prophet! Say to thy spouses (f) and thy daughters and the females, ones who believe to draw closer their (f) outer garments over themselves (f). That is more fitting so that they (f) be recognized and not be maligned. And God had been Forgiving, Compassionate
Muhammed Asad Translation:
O Prophet! Tell thy wives and thy daughters, as well as all [other] believing women, that they should draw over themselves some of their outer garments [when in public]: this will be more conducive to their being recognized [as decent women] and not annoyed. But [withal,] God is indeed much- forgiving, a dispenser of grace!
And no you wouldn't get away with abusing a slave woman
Or a slave/captive/ those whom your right hands posses in general:
Ash-Shafi’ee said (and obviously according to the Shafi'i school)
وَإِذَا اغْتَصَبَ الرَّجُلُ الْجَارِيَةَ ثُمَّ وَطِئَهَا بَعْدَ
الْغَصْبِ وَهُوَ مِنْ غَيْرِ أَهْلِ الْجَهَالَةِ أُخِذَتْ مِنْهُ
الْجَارِيَةُ وَالْعُقْرُ وَأُقِيمَ عَلَيْهِ حَدُّ الزِّنَا
If a man acquires a slave girl by force and then he rapes her, and he
is not an ignorant person, then the slave girl is taken from him. He
must pay the fine and the legal punishment for adultery will be
applied to him.
Source: Kitab Al-Umm 253
From Muwatta Malik(and according to Maliki jurisprudence):
Malik related to me from Ibn Shihab that Abd al-Malik ibn Marwan gave a judgment that the rapist had to pay the raped woman her bride- price.
Yahya said that he heard Malik say, "What is done in our community about the man who rapes a woman, virgin or non-virgin, if she is free, is that he must pay the bride-price of the like of her. If she is a slave, he must pay what he has diminished of her worth. The hadd-punishment in such cases is applied to the rapist, and there is no punishment applied to the raped woman. If the rapist is a slave, that is against his master unless he wishes to surrender him."

From Sahih Al Bukhari:
Safiya bint Ubaid said:
"A governmental male-slave tried to seduce a slave-girl from the Khumus of the war booty till he deflowered her by force against her will; therefore 'Umar flogged him according to the law, and exiled him, but he did not flog the female slave because the male-slave had committed illegal sexual intercourse by force, against her will." Az-Zuhri said regarding a virgin slave-girl raped by a free man: The judge has to fine the adulterer as much money as is equal to the price of the female slave and the adulterer has to be flogged (according to the Islamic Law); but if the slave woman is a matron, then, according to the verdict of the Imam, the adulterer is not fined but he has to receive the legal punishment (according to the Islamic Law).

Ibn Umar reported: The Messenger of Allah, peace and blessing be upon him, said:
مَنْ ضَرَبَ غُلَامًا لَهُ حَدًّا لَمْ يَأْتِهِ أَوْ لَطَمَهُ فَإِنَّ كَفَّارَتَهُ أَنْ يُعْتِقَهُ
Whoever strikes his slave without limit or slaps him, then the expiation for his sin is to emancipate him.
Source: Sahih Muslim 1657, Grade: Sahih
Suwaid ibn Muqarrin reported: He had a servant girl and someone slapped her, so he said to him:
أَمَا عَلِمْتَ أَنَّ الصُّورَةَ مُحَرَّمَةٌ فَقَالَ لَقَدْ رَأَيْتُنِي وَإِنِّي لَسَابِعُ إِخْوَةٍ لِي مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم وَمَا لَنَا خَادِمٌ غَيْرُ وَاحِدٍ فَعَمَدَ أَحَدُنَا فَلَطَمَهُ فَأَمَرَنَا رَسُولُ اللَّهِ صلى الله عليه وسلم أَنْ نُعْتِقَهُ
Did you not know that it is forbidden to strike the face? I was the seventh of my brothers during the lifetime of the Prophet and we had only one servant. One of us became enraged and slapped him, so the Prophet commanded us to set him free.

This verse of the Quran prohibits people forcing slave girls into the "sex trade":
وَلَا تُكْرِهُوا فَتَيَاتِكُمْ عَلَى الْبِغَاءِ إِنْ أَرَدْنَ
تَحَصُّنًا لِّتَبْتَغُوا عَرَضَ الْحَيَاةِ الدُّنْيَا
Do not compel your slave girls to prostitution if they desire
chastity, seeking thereby the interests of worldly life.
Surah An-Nur 24:33
While this one commands kind treatment of slaves:
وَيُطْعِمُونَ الطَّعَامَ عَلَىٰ حُبِّهِ مِسْكِينًا وَيَتِيمًا
وَأَسِيرًا إِنَّمَا نُطْعِمُكُمْ لِوَجْهِ اللَّهِ لَا نُرِيدُ مِنكُمْ
جَزَاءً وَلَا شُكُورًا
They give food in spite of love for it to the needy, the orphan, and
the captive, saying: We feed you only for the countenance of Allah. We
do not desire from you reward or gratitude.
Surat Al-Insan 76:8-9
Ibn Kathir explained this verse stating:
وَقَالَ ابْنُ عَبَّاسٍ كَانَ أُسَرَاؤُهُمْ يَوْمَئِذٍ مُشْرِكِينَ
وَيَشْهَدُ لِهَذَا أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ
وَسَلَّمَ أَمَرَ أَصْحَابَهُ يَوْمَ بَدْرٍ أَنْ يُكْرِمُوا الْأُسَارَى
فَكَانُوا يُقَدِّمُونَهُمْ عَلَى أَنْفُسِهِمْ عِنْدَ الْغَدَاءِ
وَهَكَذَا قَالَ سَعِيدُ بْنُ جُبَيْرٍ وَعَطَاءٌ وَالْحَسَنُ
وَقَتَادَةُ وَقَدْ وَصَّى رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ
وَسَلَّمَ بِالْإِحْسَانِ إِلَى الْأَرِقَّاءِ فِي غَيْرِمَا حَدِيثٍ
حَتَّى إِنَّهُ كَانَ آخِرَ مَا أَوْصَى أَنْ جَعَلَ يَقُولُ الصَّلَاةَ
وَمَا مَلَكَتْ أَيْمَانُكُمْ
Ibn Abbas said: Their captives on that day were idolaters. The
evidence for that is that the Messenger of Allah, peace and blessings
be upon him, commanded his companions to be generous to the prisoners
on the day of Badr and they would give preference to them in meals
over themselves. Such was reported by Sa’eed ibn Jubair, Ata’,
Al-Hasan, and Qatadah. The Messenger of Allah had enjoined good
treatment towards captives in more than one tradition, so often that
one of the last things he said was: Guard the prayer and those whom
your right hand possesses.

This Hadith also shows that slaves had to be treated well:
Abu Aziz ibn Umair reported:
كُنْتُ فِي الأُسَارَى يَوْمَ بَدْرٍ فَقَالَ رَسُولُ اللَّهِ صَلَّى
اللَّهُ عَلَيْهِ وَسَلَّمَ اسْتَوْصُوا بِالأُسَارَى خَيْرًا وَكُنْتُ
فِي نَفَرٍ مِنَ الأَنْصَارِ وَكَانُوا إِذَا قَدَّمُوا غَدَاءَهُمْ
وَعَشَاءَهُمْ أَكَلُوا التَّمْرَ وَأَطْعَمُونِي الْخُبْزَ بِوَصِيَّةِ
رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِيَّاهُمْ
I was among the prisoners of war on the day of Badr. The Messenger of
Allah, peace and blessings be upon him, said, “I enjoin you to treat
the captives well.” After I accepted Islam, I was among the Ansar and
when the time of lunch or dinner arrived, I would feed the prisoners
dates as I had been fed bread due to the command of the Prophet.

The Prophet (saw) also stated:
لَا يَدْخُلُ الْجَنَّةَ سَيِّئُ الْمَلَكَة
He will not enter Paradise who is evil to his slaves.

The Prophet (saw) advised Muslims:
أَطْعِمُوا الْجَائِعَ وَعُودُوا الْمَرِيضَ وَفُكُّوا الْعَانِيَ
Feed the hungry, visit the sick, and set the captives free.

Ma’rur ibn Suwaid reported: The Messenger of Allah, peace and
blessings be upon him, said:
إِخْوَانُكُمْ وَخَوَلُكُمْ جَعَلَهُمْ اللَّهُ تَحْتَ أَيْدِيكُمْ
فَمَنْ كَانَ أَخُوهُ تَحْتَ يَدَيْهِ فَلْيُطْعِمْهُ مِمَّا يَأْكُلُ
وَلْيُلْبِسْهُ مِمَّا يَلْبَسُ وَلَا تُكَلِّفُوهُمْ مَا يَغْلِبُهُمْ
فَإِنْ كَلَّفْتُمُوهُمْ فَأَعِينُوهُمْ عَلَيْهِ
Your slaves are your brothers. Allah has placed them in your hand, and
he who has his brother under him should feed him with the same food he
eats and clothe him with the same clothes he wears, and do not burden
him beyond his capacity, and if you burden him then help him.
Source: Sahih Muslim 1661, Grade: Sahih
أَطْعِمُوهُمْ مِمَّا تَأْكُلُونَ وَأَلْبِسُوهُمْ مِنْ لَبُوسِكُمْ
وَلاَ تُعَذِّبُوا خَلْقَ اللهِ عَزَّ وَجَلَّ
Feed them from the same food you eat and clothe them from the same
clothes you wear, and do not torture the creation of Allah the
Exalted.

Abu Mas’ud reported: I was beating a boy (slave) of mine when I heard
a voice from behind me:
اعْلَمْ أَبَا مَسْعُودٍ لَلَّهُ أَقْدَرُ عَلَيْكَ مِنْكَ عَلَيْهِ
Know, O Abu Mas’ud, that Allah has more power over you than you have
over him.
I turned around and it was the Messenger of Allah, peace and blessings
be upon him. I said, “O Messenger of Allah, I have freed him for the
sake of Allah.” The Prophet said:
أَمَا لَوْ لَمْ تَفْعَلْ لَلَفَحَتْكَ النَّارُ
If you had not done so, you would have been burnt in the Hellfire.

Anas ibn Malik reported:
النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَعْتَقَ صَفِيَّةَ
وَجَعَلَ عِتْقَهَا صَدَاقَهَا
The Prophet emancipated Safiya and made her freedom as her marriage
dowry.
Source: Sahih Bukhari 4798, Grade: Muttafiqun Alayhi
I showed this Hadith because it showed the Prophet doing away with the "shame" of marrying a slave.
The Quran instructs Muslims to marry slaves:
وَأَنكِحُوا الْأَيَامَىٰ مِنكُمْ وَالصَّالِحِينَ مِنْ عِبَادِكُمْ
وَإِمَائِكُمْ إِن يَكُونُوا فُقَرَاءَ يُغْنِهِمُ اللَّهُ مِن فَضْلِهِ
وَاللَّهُ وَاسِعٌ عَلِيمٌ
Marry the unmarried among you and the righteous among your male slaves and female slaves. If they should be poor, Allah will enrich them from His bounty, for Allah is Encompassing and Knowing.
Surah An-Nur 24:32
Umar condemned a man to death for raping a female captive he had acquired during war.
Harun ibn Al-Asim reported: Umar ibn Al-Khattab sent Khalid ibn
Al-Waleed with the army and Khalid sent Dirar ibn Al-Azwar along with
a company and they invadnd Dirar was impressed with her. He asked his
companions to give her to him and ed a district belonging to the tribe
of Asad. They captured a beautiful girl athey did, then he had
intercourse with her. A letter was sent to Umar and he replied:
فَكَتَبَ عُمَرُ أَنْ أَرْضِخْهُ بِالْحِجَارَةِ
He should be stoned to death.

Comments about jilbabs:
A jilbab is a loose garment that covers the body e.g: abaya. It is not a hijab. What we call a hijab know is usually referred to as a khimar. (Most pictures under jilbab will usually be a jilbab and a khimar)
Conclusion:
In conclusion, it would be illegal to abuse a slave/slave woman in the time of the Prophet (saw) the slave would have to be emancipated, the 'master' would be punished or both. It is obligatory to treat slaves fairly if not kindly and strongly recommended to free them. The people mentioned in the above tafaseer are not representative of the early Muslim community and that is why At Tabari refers to them as hypocrites.
P.S : Tabari's work is a mixture of reports of varying authenticity. He collected everything reported to him without isnaad or matn criticism. His work according to Yasir Qadhi was supposed to be an encyclopedia-type tafsir for scholars and not something for the general public.
