Narrated Ibn 'Abbas (RA):

When 'Ali (RA) married Fatimah (RA) Allah's Messenger (ﷺ) said to him, "Give her something (as dowry)." He replied, "I have nothing." He said, "Where is your Hutamiya coat of mail?" [Reported by Abu Dawud and an-Nasa'i; al-Hakim graded it Sahih (authentic)].

وَعَنِ ابْنِ عَبَّاسٍ ‏- رَضِيَ اَللَّهُ عَنْهُمَا‏- قَالَ : { لَمَّا تَزَوَّجَ عَلِيٌّ فَاطِمَةَ ‏-عَلَيْهِمَا اَلسَّلَامُ‏- .‏ قَالَ لَهُ رَسُولُ اَللَّهِ ‏- صلى الله عليه وسلم ‏-" أَعْطِهَا شَيْئًا " , قَالَ : مَا عِنْدِي شَيْءٌ .‏ قَالَ :" فَأَيْنَ دِرْعُكَ الحُطَمِيَّةُ ? } رَوَاهُ أَبُو دَاوُدَ , وَالنَّسَائِيُّ , وَصَحَّحَهُ اَلْحَاكِمُ [1]‏ .‏
