391/506 عن عطاء:"انه راى ام زفر – تلك المراة – طويلة سوداء على سلم الكعبة". وعن القاسم؛ ان عائشة اخبرته؛ ان النبي صلى الله عليه وسلم كان يقول:"ما اصاب المؤمن فما فوقها، فهو كفارة".
It is narrated from Ata that he saw a tall black woman, Umm Zafar, on the steps of the Ka'bah. It is narrated from Qasim that Sayyida Aisha (may Allah be pleased with her) informed him that the Prophet (peace and blessings be upon him) used to say that when a believer is pricked by a thorn or suffers anything greater (or lesser) than that, it becomes an expiation for him.
