It was narrated from Umm Habibah that the Messenger of Allah married her when she was in Ethiopia. An-NajaShi performed the marriage for her and gave her a dowry of four thousand, and he fitted her out from his own wealth, and sent her with Shurahbil bin Hasanah. The Messenger of Allah did not send her anything, and the dowry of his wives was four hundred Dirhams. (Using translation from Nasāʾī 3350)  

أَنَّ رَسُولَ اللهِ ﷺ «تَزَوَّجَهَا وَهِيَ بِأَرْضِ الْحَبَشَةِ زَوَّجَهَا النَّجَاشِيُّ وَأَمْهَرَهَا أَرْبَعَةَ آلَافٍ وَجَهَّزَهَا مِنْ عِنْدِهِ وَبَعَثَ بِهَا مَعَ شُرَحْبِيلِ بْنِ حَسَنَةَ وَلَمْ يَبْعَثْ إِلَيْهَا رَسُولُ اللهِ ﷺ بِشَيْءٍ وَكَانَ مَهْرُ نِسَائِهِ أَرْبَعَمِائَةِ دِرْهَمٍ»
