I am a sinner and I need forgiveness.What ayahs should I recite and what is the best way to ask for forgiveness and which time is the best to ask for forgiveness?
Similar as in any other time of the year, by repenting sincerely, stopping the sin at once, giving back what is not yours or correcting your mistake towards others (and apologizing and asking them for forgiveness) and trying never to repeat it again.
To seek forgiveness one doesn't need to recite qur'an nor to seek a special hour. Nevertheless it may be good to recite the qur'an and make du'a and dhikr all the time or seek the special hours which the prophet () and the qur'an have indicated us. Such as the hour in the day of Jumu'ah, the 1st third of the night and the time of fajr. But this is for the purpose to do good deeds instead of the sin you've committed in the hope that Allah may accept your repentance.
But, it is never good to waste time if one wants to seek forgiveness. So you should ask for forgiveness once you've come to mind that you've wronged somebody or committed a sin. It is better to repent before you won*t have time to do so!
The only special thing about Ramadan is the worship (and the special night). There are four much more important months in the Muslim Calendar the ashhur al-Hurum الأشهر الحرم (the holy months) Rajab, Dhi-l Qi'da, Dhi-l Hijja and Muharam where the counts for the deeds are multiplied or considered more important/severe (both bad and good deeds). While Ramadan is just one of the eight other (normal) months.
All of us are sinful and incomplete. Our job is to stay away from sins as much as possible and ask for fogiveness always.
In Quran Allah mentioned many prayers of HIS messengers so we can repeat them as per our situation
Best time of pray is last part of night
At jummah day, between asar and magrib
“Friday is comprised of twelve hours. There is one in which a Muslim who asks Allaah for something will have it granted to him. Seek it in the last hour after
Asr.” [Sunan Abî Dâwûd (1048), Sunan al-Nasâ’î (1389) and Mustadrak al-Hâkim(1032)]
A similar hadîth was related by Anas (may Allaah be pleased with him) that the Prophet (peace and blessings of Allaah be upon him) said: “Seek the anticipated hour of Friday afterAsr until sunset” [Sunan al-Tirmidhî (489)] Al-Tirmidh
