When Ali married Fatimah, the Prophet ﷺ said to him: Give her something. He said: I have nothing with me. He said: Where is your Hutamiyyah (coat of mail).  

لَهُ رَسُولُ اللَّهِ ﷺ أَعْطِهَا شَيْئًا قَالَ مَا عِنْدِي شَىْءٌ قَالَ أَيْنَ دِرْعُكَ الْحُطَمِيَّةُ  

When Ali married Fatimah, daughter of the Messenger of Allah ﷺ, he intended to have intercourse with her. The Messenger of Allah ﷺ prohibited him to do so until he gave her something. Ali said: I have nothing with me, Messenger of Allah. The Prophet ﷺ said: Give her your coat of mail. So he gave her his coat of mail, and then cohabited with her.  

عَنْ رَجُلٍ مِنْ أَصْحَابِ النَّبِيِّ ﷺ أَنَّ عَلِيًّا عَلَيْهِ السَّلاَمُ لَمَّا تَزَوَّجَ فَاطِمَةَ بِنْتَ رَسُولِ اللَّهِ ﷺ وَ ؓ أَرَادَ أَنْ يَدْخُلَ بِهَا فَمَنَعَهُ رَسُولُ اللَّهِ ﷺ حَتَّى يُعْطِيَهَا شَيْئًا فَقَالَ يَا رَسُولَ اللَّهِ لَيْسَ لِي شَىْءٌ فَقَالَ لَهُ النَّبِيُّ ﷺ أَعْطِهَا دِرْعَكَ فَأَعْطَاهَا دِرْعَهُ ثُمَّ دَخَلَ بِهَا  

A similar tradition has also been transmitted by Ibn 'Abbas through a different chain of narrators.  

عَنِ ابْنِ عَبَّاسٍ مِثْلَهُ  

The Messenger of Allah ﷺ commanded me to send a woman to her husband before he gave something to her. Abu Dawud said: The narrator Khaithamah did not hear (any tradition) from 'Aishah.  

أَمَرَنِي رَسُولُ اللَّهِ ﷺ أَنْ أُدْخِلَ امْرَأَةً عَلَى زَوْجِهَا قَبْلَ أَنْ يُعْطِيَهَا شَيْئًا  

A woman who marries on a dower or a reward or a promise before the solemnisation of marriage is entitled to it; and whatever is fixed for her after solemnisation of marriage belongs to whom it is given. A man is more entitled to receive a thing given as a gift on account of his daughter or sister (than other kinds of gifts).  

قَالَ رَسُولُ اللَّهِ ﷺ أَيُّمَا امْرَأَةٍ نُكِحَتْ عَلَى صَدَاقٍ أَوْ حِبَاءٍ أَوْ عِدَةٍ قَبْلَ عِصْمَةِ النِّكَاحِ فَهُوَ لَهَا وَمَا كَانَ بَعْدَ عِصْمَةِ النِّكَاحِ فَهُوَ لِمَنْ أُعْطِيَهُ وَأَحَقُّ مَا أُكْرِمَ عَلَيْهِ الرَّجُلُ ابْنَتُهُ أَوْ أُخْتُهُ
