Consuming Halal
On the authority of Abu Hurairah, The Messenger of Allah (peace be upon him) said:
“Allah the Almighty is good and accepts only that which is good. Allah has commanded the faithful to do that which he commanded the messengers, and the Almighty has said: ‘O ye messengers! Eat of the good things and do right.’ And Allah the Almighty has said, ‘O ye who believe! Eat of the good things wherewith We have provided you.’”
Then the Prophet mentioned [the case of] a man who, having journeyed far, is disheveled and dusty and who spreads out his hands to the sky [saying] : "O Lord! O Lord!" Meanwhile, his (the traveller’s) food is unlawful, his drink unlawful, his clothing unlawful, and he is nourished unlawfully; so how can he be answered!
