What is awwabin prayer? What are awwabin prayer benefits?
Ibn Umar (may Allah be pleased with them) narrates that the Messenger of Allah would perform two rak’ahs of supererogatory prayer after the obligatory evening prayer. (Bukhari, Tahajjud, 29) This is called “awwabin” prayer.
The word awwabin is the plural form of awwab which means “the one who turns to Allah and repents.” Anyone who realizes his/her mistake, turns to and obeys Allah, and then repents for his/her sins and does good deeds can be called awwab. Those who pray six, four, or two rak’ahs – or according to some reports without any specified rak’ahs – after evening prayer are, too, called “awwabin.”
