Sunan an-Nasa'i, Volume 3, Book 24, Hadith 3062 (DarusSalam) ⓘ

It was narrated from Yajya bin Al-Husain that his grandmother, Umm Husain said: "I perfomed Hajj during the Hajj of the Prophet. I saw Bilal hodling on the reins of his she-camel, and Usmah bin Zaid hodling his garment ouver him to shade him from the heat, while he was in Ihram, until he had stoned Jamratual Aqabah. Then he addressed the people and praised Allahy, and mentioned many things."

أَخْبَرَنِي عَمْرُو بْنُ هِشَامٍ، قَالَ حَدَّثَنَا مُحَمَّدُ بْنُ سَلَمَةَ، عَنْ أَبِي عَبْدِ الرَّحِيمِ، عَنْ زَيْدِ بْنِ أَبِي أُنَيْسَةَ، عَنْ يَحْيَى بْنِ الْحُصَيْنِ، عَنْ جَدَّتِهِ أُمِّ حُصَيْنٍ، قَالَتْ حَجَجْتُ فِي حَجَّةِ النَّبِيِّ صلى الله عليه وسلم فَرَأَيْتُ بِلاَلاً يَقُودُ بِخِطَامِ رَاحِلَتِهِ وَأُسَامَةَ بْنَ زَيْدٍ رَافِعٌ عَلَيْهِ ثَوْبَهُ يُظِلُّهُ مِنَ الْحَرِّ وَهُوَ مُحْرِمٌ حَتَّى رَمَى جَمْرَةَ الْعَقَبَةِ ثُمَّ خَطَبَ النَّاسَ فَحَمِدَ اللَّهَ وَأَثْنَى عَلَيْهِ وَذَكَرَ قَوْلاً كَثِيرًا ‏.‏
