Narrated Umm Hani bint Abu Talib:
"The Messenger of Allah (ﷺ) proposed to me, but I asked him to excuse me. Then Allah [Most High] revealed: 'Verily We have made lawful to you your wives, to whom you have paid their due, and those whom your right hand possess - whom Allah has given to you, and the daughters of your paternal uncles, and the daughters of your paternal aunts, and the daughters of your maternal uncles, and the daughters of your maternal aunts, who migrated with you, and a believing woman if she offers herself to the Prophet... (33:50)' She said: "So I was not lawful for him because I did not perform Hijrah; I was one of the Tulaqa (those that accepted Islam after the conquest of Makkah).'"
