Hameed bin Abi Hameed حميد بن أبي حميد الطويل · The Book on Salat (Prayer)

"Allah's Messenger performed Salat during his illness behind Abu Bakr while seated, wrapped in a garment."

Allah's Messenger said: "Indeed I hear the crying of a small boy while I am in Salat, so I shorten it in fear that his mother may be tormented."
