About Your First Question:
The exact hadeeth wording and its reference:
Muslim, Ahmad, and al-Tirmidhi narrated from Ibn ‘Abbas that the Prophet (peace and blessings of Allah be upon him) said:
“The evil eye is real and if anything were to overtake the divine decree, it would be the evil eye. When you are asked to take a bath (to provide a cure) from ...
well, on the other case. some of my country's ulama said that brushing teeth is makruh so they often tell to not doing that around fasting. but someother says it's welcome for us to do that as long as the water or the paste is not swallowed into our body.
Brushing your teeth during fasting is not hampered your fast until or unless you swallowed the toothpaste. You can use any toothpaste but be careful don't gulped it down. Dental hygiene paid heed to as one following the strict sovereignty during the month of blessings holy Ramadan
Brushing the teeth during the fast will not break the fast until you swallow it. So be careful during brushing, don't swallow the toothpaste and water when you brush your teeth. But it can be broken when you brush your teeth due to hard toothbrush,it hurts the gums the blood come out from the gums and if that blood mixed with saliva and you swallow it then ...
During Iddat women not allowed to even talk with some "Na Mehram", Even she is not allowed to see "Na Mehram".Then how can a women can be committed to someone or get engaged with someone.So this is not allowed during the time period of Iddat ,yes it is allowed after Iddat duration.
I found the hadith on this website.
And found fatwas saying that this hadith doesn't exist in any hadith compilation.
It is rather mentioned as a quote of Ka'ab al-Ahbaar which he found in the Torah according to ibn 'Arabi ابن عربي in his al-Futuhaat al-Makiyyah الفتوحات المكية and in al-Mustatraf min Kulli fannin Mustadhraf المستطرف في كل فن مستظرف of al-...
It is hadith that is not sahih itself, but has some doubt because of which it is Hassan (like maybe one of the narrators is truthful but is said to have poor memory).
However there exists another Hassan or Sahih hadith with different sanad that says the same. Because of the existence of this other sanad we can be sure of the authenticity of the hadith.
It can mean both. From the root ص ل و , it can mean:
to perform the salat
to bless someone i.e. صَلَّى ٱللهُ عَلَيْهِ وَآلِهِ meaning ‘Blessings be upon him and progeny
From the Hadith:
يَقُولُ سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ " إِذَا سَمِعْتُمُ الْمُؤَذِّنَ فَقُولُوا مِثْلَ مَا يَقُولُ وَصَلُّوا عَلَىَّ ...
The hadith actually appears in both sahihs:
in Sahih al-Bukhari:
In the book of Agriculture/Chapter: If a person invests the money of someone else in cultivation.
In the book good Manners and Form (Al-Adab)/Chapter: The invocation of the person who is dutiful to his parents if fulfilled.
In the book of Sales and Trade/Chapter: If somebody buys something for ...
*JamI' al-Bayan 'an ta'wil ayi al-Qur'an جامع البيان عن تأويل آي القرآن: Tafsir at-Tabari**
The tafssir of imam ibn Jarir at-Tabari is among the first Tafssir books and one of the best examples of at-Tafssir bil Ma'athur (see for example Are al-Tabari's Commentary (10th century) & Ibn Kathir's Commentary (14th century) on the Qur'an ...
Ablution is sunnah we are blessed with this before every prayer. But it's not necessary to perform ablution before every prayer if you already have it. But it's good to perform ablution before every prayer if you are on road and any other place where water is not available you can pray with your last performed wadu if it is still you have.
And the other side ...
The hadith doesn't explicitly say that 1500 sahabi made the ablution, but it says that this amount was present when this happened. So we can't exclude that some of them have been in a pure state. Note that scholars such as ibn Hajar discussed the amount as the reports seem to have a certain difference.
The hadith can actually be explained by another version ...
Technically speaking, tears contain water mixed with enzymes so swallowing such will break your fast. If you swallow anything that can break your fast whether by accident and you havent forgotten that you are fasting then your fast is broken, void. If you forgot that you were fasting and you did swallow anything that break your fast then your fast is not ...
In a few words;
If you swallowed them intentionally, the fast is rendered broken.
If you swallowed them accidentally, the fast is rendered broken and should be made up.
If you swallowed them forgetfully, then the fast still valid and you can continue.
