وَعَنْ أَنَسٍ: أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ كَانَ شَاكِيًا فَخَرَجَ يَتَوَكَّأُ عَلَى أُسَامَةَ وَعَلَيْهِ ثَوْبُ قِطْرٍ قَدْ تَوَشَّحَ بِهِ فَصَلَّى بهم. رَوَاهُ فِي شرح السّنة

Anas told that when the Prophet was ill he came out leaning on Usama, wearing a striped garment with an end over his left shoulder, and led them in the prayer. It is transmitted in Sharh as-sunna .
