Sunan Ibn Majah, Hadith 549 ⓘ
It was narrated from Abu Buraidah from his father that: An-Najashi gave the Prophet a gift of a pair of plain black leather socks. He put them on, then he (performed ablution and) wiped over them.
حَدَّثَنَا عَلِيُّ بْنُ مُحَمَّدٍ، حَدَّثَنَا وَكِيعٌ، حَدَّثَنَا دَلْهَمُ بْنُ صَالِحٍ الْكِنْدِيُّ، عَنْ حُجَيْرِ بْنِ عَبْدِ اللَّهِ الْكِنْدِيِّ، عَنِ ابْنِ بُرَيْدَةَ، عَنْ أَبِيهِ، أَنَّ النَّجَاشِيَّ، أَهْدَى لِلنَّبِيِّ ـ صلى الله عليه وسلم ـ خُفَّيْنِ أَسْوَدَيْنِ سَاذَجَيْنِ فَلَبِسَهُمَا ثُمَّ تَوَضَّأَ وَمَسَحَ عَلَيْهِمَا .
