SURAH AN-NASR (THE HELP)
1,2When the help of Allah and the conquest come and when you see the people entering into the religion of Allah in groups, 3immediately purify Him from all deficiencies with the praise of your Rabb and ask Him for forgiveness. Indeed, He is the One Who accepts repentances much, gives many opportunities to repent, ever.
Allah is the One Who knows best the truth and His own purpose.
Only to Allah belongs perfection.
