It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him), he says: We were in the mosque with the Messenger of Allah (peace and blessings be upon him), when he (peace and blessings be upon him) stood up, we also stood up. Meanwhile, a Bedouin came and said: O Muhammad! Give me something. The Prophet (peace and blessings be upon him) said: No, and I seek forgiveness from Allah. He pulled the Prophet (peace and blessings be upon him), which caused a scratch to the Prophet (peace and blessings be upon him). The companions wanted to do something to him, but the Prophet (peace and blessings be upon him) said: Leave him. Then the Prophet (peace and blessings be upon him) gave him something. The Prophet (peace and blessings be upon him) would also swear in these words: Lā wa astaghfirullāh (No, and I seek forgiveness from Allah).
