Musnad Ahmad #777
Musnad 'Ali Ibn Abi Talib
The Arabic includes the chain of narration (sanad) and the collector's commentary; the English translation shows the Prophet's words only.
حَدَّثَنَا عَفَّانُ، حَدَّثَنَا حَمَّادٌ، حَدَّثَنَا عَطَاءُ بْنُ السَّائِبِ، عَنْ أَبِيهِ، عَنْ عَلِيٍّ، رَضِيَ اللَّهُ عَنْهُ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ لَمَّا زَوَّجَهُ فَاطِمَةَ بَعَثَ مَعَهَا بِخَمِيلَةٍ وَوِسَادَةٍ مِنْ أَدَمٍ حَشْوُهَا لِيفٌ وَرَحَيَيْنِ وَسِقَاءٍ وَجَرَّتَيْنِ.
It was narrated from `Ali (رضي الله عنه) that when the Messenger of Allah (ﷺ) gave Fatimah to him in marriage, he sent with her a velvet garment, a leather pillow stuffed with palm fibre, two millstones, a waterskin and two earthenware jars.
