Bilal ibn Ka'b al-'Ukki said, "We - Ibrahim ibn Adham, 'Abdu'l-'Aziz ibn Qarir, Musa ibn Yasar and I - visited Yahya ibn Hassan (al-Bakri al-Filistini) in his village. He brought us some food, but Musa held back because he was fasting. Yahya said, 'We had a man with the kunya of Abu Qursafa from the Banu Kinana who had been one of the Companions of the Prophet, may Allah bless him and grant him peace, and he was in this mosque for forty years. He would fast one day and break the fast the next day, My father had a son born to him and he invited this man on the day that he was fasting and he broke his fast.' Ibrahim stood up and swept him with cloak and Musa broke his fast."
