Sahih Muslim 419 d
Kitabu cha Swala
If The Imam Experiences An Excuse, From Illness, Or Travelling, Etc. He May Appoint Someone Else To Lead The People In Prayer; The One Who Offers Prayer Behind The Imam Sitting Because He Is Unable To Stand Must Stand If He Is Able To Do So; And The Abrogation Of Sitting Behind A Sitting Imam For Those Who Are Able To Stand
Anas reported: The Messenger of Allah (ﷺ) did not come to us for three days. When the prayer was about to start. Abu Bakr stepped forward (to lead the prayer), and the Messenger of Allah (ﷺ) lifted the curtain. When the face of the Messenger of Allah (ﷺ) became visible to us, we (found) that no sight was more endearing to us than the face of the Messenger of Allah (ﷺ) as it appeared to us. The Messenger of Allah (ﷺ) with the gesture of his hand directed Abu Bakr to step forward (and lead the prayer). The Messenger of Allah (ﷺ) then drew the curtain, and we could not see him till he died.
