Abu Hurairah said; The Messenger of Allah ﷺ got up for the prayer and we also stood up along with him. A Bedouin said said during prayer; O Allah, show mercy to me and to Muhammed and do not show mercy to anyone along with us. When the Messenger of Allah ﷺ uttered the salutation, he said to the Bedouin; you narrowed down a vast (thing). By this he meant the mercy of Allah.
