Bismillah Walhamdulillah Was Salaatu Was Salaam ‘ala Rasulillah
Narrated Abu Said Al-Khudri (Radi-Allahu ‘anhu):
The Prophet (Sallallahu ‘Alaihi Wa Sallam) said to his companions, “Is it difficult for any of you to recite one third of the Qur’an in one night?” This suggestion was difficult for them so they said, “Who among us has the power to do so, O Allah’s Apostle?” Allah’s Apostle (Sallallahu ‘Alaihi Wa Sallam) replied, “ ‘Allah (the) One, the Self-Sufficient Master Whom all creatures need.’ (Surat Al-Ikhlas 112.1–to the End) is equal to one third
of the Qur’an.”
