A'isha reported:
The Messenger of Allah ( صلی اللہ علیہ وسلم ) sent a man in charge of an expedition and he would recite for his Companions during their prayer, ending (recitation) with: Say, He is God, One. When they returned mention was made of it to the Messenger of Allah ( صلی اللہ علیہ وسلم ). He (the Holy Prophet) told them to ask him why he had done like that. So they asked him and he said: Verily, it is an attribute of the Compassionate One, and (for this reason) I love to recite it. The Messenger of Allah ( صلی اللہ علیہ وسلم ) thereupon said: Inform him that Allah loves him.
