Musnad Ahmad 1165:4

Musa ibn Dawud narrated to us, Abd al-Aziz ibn Abi Salamah narrated to us, from Humayd, from Anas, from Umm al-Fadl bint al-Harith, who said: "The Messenger of Allah (may Allah bless him and grant him peace) led us in prayer in his house, wrapped in a garment, for the Maghrib prayer. He recited 'al-Mursalat' (The Emissaries). He did not pray any prayer after it until he was taken (passed away), may Allah bless him and grant him peace."
