It was narrated from Husain bin ‘Ali that his mother, Fatimah the daughter of the Messenger of Allah (ﷺ), said: “The Messenger of Allah (ﷺ) said: ‘A man has no one to blame but himself, if he goes to bed with a smell emanating from his hand.’”
It was narrated from Abu Hurairah that the Prophet (ﷺ) said: “If anyone of you goes to bed with a smell emanating from his hand, and he does not wash his hand, and something happens to him, he should not blame anyone but himself.”
