The Prophet ﷺ saw me sitting in the sun while he was delivering the sermon, so he instructed me to move into the shade.
حدثنا وكيع قال حدثنا ابن أبي خالد
رآني النبي ﷺ وهو يخطب وأنا في الشمس فأمرني فحولت إلى الظل
Its isnad is sahih. Ibn Abu Khalid is Ismail, and the hadith was previously mentioned at 10404.
