عَنْ أُمِّ حَبِيبَةَ: أَنَّهَا كَانَتْ تَحْتَ عَبْدِ اللَّهِ بْنِ جَحْشٍ فَمَاتَ بِأَرْضِ الْحَبَشَةِ فَزَوَّجَهَا النَّجَاشِيُّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَأَمْهَرَهَا عَنهُ أَرْبَعَة آلَاف. وَفِي رِوَايَة: أَرْبَعَة دِرْهَمٍ وَبَعَثَ بِهَا إِلَى رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ مَعَ شُرَحْبِيل بن حَسَنَة. رَوَاهُ أَبُو دَاوُد وَالنَّسَائِيّ
Translation
Anas said that Abu Talha married Umm Sulaim, the dower between them being acceptance of Islam. Umm Sulaim had become a Muslim before Abu Talha, and when he asked her in marriage she said, "I have become a Muslim, so if you become one I shall marry you.” He then accepted Islam and that was the dower arranged between them. Nasa’i transmitted it.
