It was narrated from ‘Ata’ bin Sa’ib from his father, from ‘Ali that the Messenger of Allah (ﷺ) came to ‘Ali and Fatimah, when they were covered with a Khamil belonging to them. And a Khamil is a white velvet made of wool. The Messenger of Allah (ﷺ) had given this to them as a wedding gift, along with a pillow stuffed with Idhkhir* and a water skin.

حَدَّثَنَا وَاصِلُ بْنُ عَبْدِ الأَعْلَى، حَدَّثَنَا مُحَمَّدُ بْنُ فُضَيْلٍ، عَنْ عَطَاءِ بْنِ السَّائِبِ، عَنْ أَبِيهِ، عَنْ عَلِيٍّ، أَنَّ رَسُولَ اللَّهِ ـ صلى الله عليه وسلم ـ أَتَى عَلِيًّا وَفَاطِمَةَ وَهُمَا فِي خَمِيلٍ لَهُمَا - وَالْخَمِيلُ الْقَطِيفَةُ الْبَيْضَاءُ مِنَ الصُّوفِ - قَدْ كَانَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ جَهَّزَهُمَا بِهَا وَوِسَادَةٍ مَحْشُوَّةٍ إِذْخِرًا وَقِرْبَةٍ .
