Surah an-Nasr was revealed in Madinah and it has 3 ayaat.
It is narrated that whoever recites this surah in compulsory prayers will always be victorious over his enemies. On the Day of Judgement he will be given a book in which it will be written that he is free from hellfire.
Recitation of this surah in the prayers ensures that the prayers are accepted.
The one who recites this surah frequently is held in the same status as those who were with the Holy Prophet (s.a.w.) when Makkah was conquered.
May Allah grant us these benefits, Aamen.
