Yahya related to me from Malik from Abd al Karim ibnAbi'l-Mukhariq al-Basri from Said ibn Jubayr that Abdullah ibn Abbasslept, and when he woke up, he said to his servant, "Go and see whatthe people have done," (by that time his sight had gone.) The servantwent out and returned saying, "The people have left from subh," soAbdullah ibn Abbas got up and prayed witr and then prayed subh.
