Sulaiman bin Yasar (may Allah have mercy on him), the freed slave of Maymunah bint Al-Harith (may Allah be pleased with her), narrates that the Prophet Muhammad (ﷺ) sent his freed slave Abu Rafi‘ (may Allah be pleased with him) and an Ansari companion; both of them arranged the marriage with Maymunah bint Al-Harith (may Allah be pleased with her) on behalf of the Messenger of Allah (ﷺ) as his representatives. At that time, the Messenger of Allah (ﷺ) was in Madinah. This happened before he set out for (the journey of) ‘Umrah al-Qada.
