حدثني سويد بن سعيد، حدثني حفص بن ميسرة، عن العلاء بن عبد الرحمن، عن أبيه، عن أبي هريرة، أن رسول الله صلى الله عليه وسلم قال " رب أشعث مدفوع بالأبواب لو أقسم على الله لأبره " .
Abu Huraira reported Allah's Messenger (may peace he upon him) as saying: Many a person with disheveled hair and covered with dust is turned away from the doors (whereas he is held in such a high esteem by Allah) that if he were to adjure in the name of Allah (about anything) Allah would fulfil that.
