Abu Darda' (Allaah be pleased with him) reported: We set out during the month of Ramadan with the Messenger of Allaah (sallAllaahu alayhi wa sallam) in such an intense heat that one of us would place his hand over his head (in order to protect himself) against the excessive heat, and none among us was observing the fast, except the Messenger of Allaah (sallAllaahu alayhi wa sallam) and 'Abdullah b. Rawaha.
