Sahih Muslim , Hadith 2622 ⓘ
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.
حَدَّثَنِي سُوَيْدُ بْنُ سَعِيدٍ، حَدَّثَنِي حَفْصُ بْنُ مَيْسَرَةَ، عَنِ الْعَلاَءِ بْنِ عَبْدِ الرَّحْمَنِ، عَنْ أَبِيهِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " رُبَّ أَشْعَثَ مَدْفُوعٍ بِالأَبْوَابِ لَوْ أَقْسَمَ عَلَى اللَّهِ لأَبَرَّهُ " .
