حَدَّثَنَا كَثِيرُ بْنُ عُبَيْدٍ الْحِمْصِيُّ، حَدَّثَنَا أَبُو حَيْوَةَ، عَنْ شُعَيْبٍ، - يَعْنِي ابْنَ أَبِي حَمْزَةَ - حَدَّثَنِي غَيْلاَنُ بْنُ أَنَسٍ، حَدَّثَنِي مُحَمَّدُ بْنُ عَبْدِ الرَّحْمَنِ بْنِ ثَوْبَانَ، عَنْ رَجُلٍ، مِنْ أَصْحَابِ النَّبِيِّ صلى الله عليه وسلم أَنَّ عَلِيًّا عَلَيْهِ السَّلاَمُ لَمَّا تَزَوَّجَ فَاطِمَةَ بِنْتَ رَسُولِ اللَّهِ صلى الله عليه وسلم وَرَضِيَ اللَّهُ عَنْهَا أَرَادَ أَنْ يَدْخُلَ بِهَا فَمَنَعَهُ رَسُولُ اللَّهِ صلى الله عليه وسلم حَتَّى يُعْطِيَهَا شَيْئًا فَقَالَ يَا رَسُولَ اللَّهِ لَيْسَ لِي شَىْءٌ ‏.‏ فَقَالَ لَهُ النَّبِيُّ صلى الله عليه وسلم ‏"‏ أَعْطِهَا دِرْعَكَ ‏"‏ ‏.‏ فَأَعْطَاهَا دِرْعَهُ ثُمَّ دَخَلَ بِهَا ‏.‏

Muhammad ibn Abdur Rahman ibn Thawban reported on the authority of a man from the Companions of the Prophet (PBUH): When Ali married Fatimah, daughter of the Messenger of Allah (PBUH), he intended to have intercourse with her. The Messenger of Allah (PBUH) prohibited him to do so until he gave her something. Ali said: I have nothing with me, Messenger of Allah. The Prophet (PBUH) said: Give her your coat of mail. So he gave her his coat of mail, and then cohabited with her. Translation Not Available
