Al-Adab Al-Mufrad, Hadith 453 ⓘ
It is reported that Habba ibn Khalid and Sawa' ibn Khalid came to the Prophet, may Allah bless him and grant him peace, while he was repairing a wall - or a building - of his, and they helped him.
حَدَّثَنَا سُلَيْمَانُ بْنُ حَرْبٍ، قَالَ: حَدَّثَنَا جَرِيرُ بْنُ حَازِمٍ، عَنِ الأَعْمَشِ، عَنْ سَلاَّمِ بْنِ شُرَحْبِيلَ، عَنْ حَبَّةَ بْنِ خَالِدٍ، وَسَوَاءَ بْنِ خَالِدٍ، أَنَّهُمَا أَتَيَا النَّبِيَّ صلى الله عليه وسلم وَهُوَ يُعَالِجُ حَائِطًا أَوْ بِنَاءً لَهُ، فَأَعَانَاهُ.
