Abu Huraira reported: The Messenger of Allah, peace and blessings be upon him, said, “O people, Allah is pure and He accepts only what is pure. Verily, Allah has commanded the believers as He commanded His Messengers. Allah said: O Messengers, eat from good things and act righteously, for I know what you do (23:51). Allah said: O you who believe, eat from good things We have provided for you.” (2:172) Then the Prophet mentioned a man who traveled far, becoming disheveled and dusty and he raises his hands to the sky, saying, “O Lord! O Lord!” while his food is unlawful, his drink is unlawful, his clothing is unlawful, and he is nourished by the unlawful, so how can he be answered?
