Abu Huraira reported: The Messenger of Allah, peace and blessings be upon him, said, “O people, Allah is purely good, and He only accepts what is purely good. Verily, Allah has commanded the believers as He has commanded His Messengers. Allah said: O Messengers, eat from wholesome foods and act righteously, for I know what you do (23:51). And Allah said: O you who believe, eat from wholesome food We have provided for you,” (2:172). Then, the Prophet mentioned a man who traveled far, becoming disheveled and dusty, and he raised his hands to the sky, saying, “O Lord! O Lord!” Yet 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?
