Dialects and Readings of the Qur'an (Kitab Al-Huruf Wa Al-Qira'at)
Dawud :: Book 30 : Hadith 3967
Narrated Abdullah ibn Umar:
Atiyyah ibn Sa'd al-Awfi said: I recited to Abdullah ibn Umar the verse: "It is Allah Who created you in a state of (helplessness) weakness (min da'f)." He said: (Read) min du'f. I recited it to the Apostle of Allah (peace_be_upon_him) as you recited it to me, and he gripped me as I gripped you.
