The Messenger of Allah ﷺ said, "Many a disheveled person, turned away at doors, if he were to swear an oath by Allah, Allah would fulfill it for him."
أن رسول الله ﷺ قال: رب أشعث مدفوع بالأبواب، لو أقسم على الله لأبره.
Muslim narrated it in the Book of Righteousness, Kinship Ties, and Manners (2622), from Suwayd bin Saeed, who said, "Hafs bin Maysara narrated to me," from Ala bin Abdul-Rahman, from his father, from Abu Hurairah, who related it.
