It is narrated from the Mother of the Believers, Sayyidah Aishah (may Allah be pleased with her), that she said: I heard the Messenger of Allah (peace and blessings be upon him) say: "Whoever performs the Fajr prayer, or he (peace and blessings be upon him) used the word 'the morning prayer', then remains sitting in the same place, does not occupy himself with any idle talk of worldly matters, but rather remains engaged in the remembrance of Allah until he performs the four rak'ahs of Duha, he comes out of his sins (pure and clean) as he was on the day his mother gave birth to him, with no sin remaining on him."
