Yahya related to me from Malik that he had heard that Abdullah ibn Abbas and Ubada ibn as-Samit and al-Qasim ibn Muhammad and Abdullah ibn Amir ibn Rabia had all prayed witr after the break of dawn.
Muwatta Malik Book 7, Hadith 24
← Previous Hadith Yahya related to me from Malik from Abd al Karim ibn Abi'l-Mukhariq al-Basri from Said ibn Jubayr that Abdullah ibn Abbas slept, and when he woke up, he said to his servant, "Go and see what the people have done," (by that time his sight had gone.) The servant went out and returned saying, "The people have left from subh," so Abdullah ibn Abbas got up and prayed witr and then prayed subh.
