Surah al-Anfaal was revealed in Madinah and it has 75 verses.
In the commentary of Majma’ul Bayaan, it is narrated from Imam Ja’far as-Sadiq (a.s.) that whoever recites surah al-Anfaal and surah at-Tawba every month, he will be protected from being a hypocrite and will be counted among the followers of Ameerul Mu’mineen.
The Holy Prophet (s.a.w) said that he will, on the Day of Judgement, intercede for the person who recites this surah and will bear witness that the reciter of this surah was free from hypocrisy.
Keeping surah al-Anfaal in your possession at all times ensures that you get your rights that have been taken from you and your legitimate desires are fulfilled.
May Allah increase us in knowledge of the Quran and Sunnah!
