[Machine] I heard Muhammad bin Abdullah bin Numair saying that Buthaynah bint Ad-Dahhak, the sister of Thabit, was the one whom Muhammad bin Muslimah proposed to.  

سَمِعْتُ مُحَمَّدَ بْنَ عَبْدِ اللهِ بْنِ نُمَيْرٍ يَقُولُ بُثَيْنَةُ بِنْتُ الضَّحَّاكِ أُخْتُ ثَابِتٍ وَهِيَ الَّتِي خَطَبَهَا مُحَمَّدُ بْنُ مَسْلَمَةَ  

[Machine] He used to give charity with meat for three years, so I presented it to Aisha and she kept it until the Messenger of Allah ﷺ entered. Then he said, "What is this meat?" She said, "It is meat that I give as charity to the poor." He said, "It is charity for Barira and a gift for us." She said, "And I have written on nine papers." Aisha said, "If you want, I will count it for them as one." I said, "They do not say anything unless they stipulate loyalty." So the Prophet ﷺ said, "Stipulate and stipulate, for loyalty belongs to those who free slaves." She said, "So I was freed and I had the choice."
