Umm Husayn reported,

I heard her say, "I performed the Farewell Pilgrimage with the Messenger of Allah ﷺ. I saw him after he had stoned Jamrat al-Aqaba and was leaving on his mount, with Bilal and Usama beside him. One of them was leading his mount, while the other was holding up a garment over the head of the Messenger of Allah ﷺ to shield him from the sun."She said, "The Messenger of Allah ﷺ spoke at length, and then I heard him say, 'If a mutilated slave," and I think she said, 'a black slave,' is placed in authority over you and leads you according to the Book of Allah the Exalted, then listen to him and obey.'"

Muslim 3138

و حدثني سلمة بن شبيب حدثنا الحسن بن أعين حدثنا معقل عن زيد بن أبي أنيسة عن يحيى بن حصين

عن جدته أم الحصين قال

سمعتها تقول حججت مع رسول الله ﷺ حجة الوداع فرأيته حين رمى جمرة العقبة وانصرف وهو على راحلته ومعه بلال وأسامة أحدهما يقود به راحلته والآخر رافع ثوبه على رأس رسول الله ﷺ من الشمس قالت فقال رسول الله ﷺ قولا كثيرا ثم سمعته يقول إن أمر عليكم عبد مجدع حسبتها قالت أسود يقودكم بكتاب الله تعالى فاسمعوا له وأطيعوا
