"I said to 'Aishah: 'Among us there are two men, one of whom hastens Iftar and delays Sahur, and the other delays Iftar and hastens Sahur.' She said; 'Which of them is the one who hastens Iftar and delays Sahur?' I said: "Abdullah bin Masud.' She said; 'This is what the Messenger of Allah used to do."'
