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.

وَعَنْ أَنَسٍ قَالَ: تَزَوَّجَ أَبُو طَلْحَةَ أُمَّ سُلَيْمٍ فَكَانَ صَدَاقُ مَا بَيْنَهُمَا الْإِسْلَامَ أَسْلَمَتْ أُمُّ سُلَيْمٍ قَبْلَ أَبِي طَلْحَةَ فَخَطَبَهَا فَقَالَتْ: إِنِّي قَدْ أَسْلَمْتُ فَإِنْ أَسْلَمْتَ نَكَحْتُكَ فَأَسْلَمَ فَكَانَ صدَاق مَا بَينهمَا. رَوَاهُ النَّسَائِيّ
