Mishkat al-Masabih #2033

‘Ā’isha said that the Prophet sent a man in charge of an expedition and he would recite for his companions during their prayer, finishing with “Say, He is God, One.” When they returned they mentioned that to the Prophet, and he told them to ask him why he did that. They asked him and he replied, “Because it is a description of the Com­passionate One, and I like to recite it.” Then the Prophet said, “Tell him that God loves him.” (Bukhārī and Muslim.)
