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. (Using translation from Ibn Mājah 549)
أَنَّ النَّجَاشِيَّ أَهْدَى إِلَى النَّبِيِّ ﷺ خُفَّيْنِ أَسْوَدَيْنِ سَاذَجَيْنِ فَلَبِسَهُمَا ثُمَّ تَوَضَّأَ وَمَسَحَ عَلَيْهِمَا
