It was narrated from Abu Salamah that :Abu Hurairah said: "The Messenger of Allah (ﷺ) stood up to pray and we stood up with him. A Bedouin said- while he was praying- 'O Allah, have mercy on me and Muhammad and do not have mercy on anyone else.' When the Messenger of Allah (ﷺ) said the Salam, he said to the Bedouin: 'You have limited something vast," meaning the mercy of Allah (SWT)
