2:172Al-Baqara

It is a food which Allah provided you (so eat it).

O people, Allah is Good and He therefore, accepts only that which is good. And Allah commanded the believers as He commanded the Messengers by saying: "O Messengers, eat of the good things, and do good deeds; verily I am aware of what you do" (xxiii. 51). And He said: "O those who believe, eat of the good things that We gave you" (ii. 172). He then made a mention of a person who travels widely, his hair disheveled and covered with dust. He lifts his hand towards the sky (and thus makes the supplication): "O Lord, O Lord," whereas his diet is unlawful, his drink is unlawful, and his clothes are unlawful and his nourishment is unlawful. How can then his supplication be accepted?

“Eat, with trust in Allah and reliance upon Allah.”

that the Messenger of Allah (ﷺ) said: "O you people! Indeed Allah is Tayyib (good) and he does not accept but what is good. And indeed Allah ordered the believers with what He ordered the Messengers. He (ﷺ) said: 'O you Messengers! Eat of the good things and do righteous deeds. Verily I am well acquainted with what you do (23:51).' And He said: 'O you who believe! Eat from the good things We have provided you (2:172).' He said: "And he mentioned a man: 'Who is undertaking a long journey, whose hair is dishevelled and he is covered with dust. He raises his hands to the heavens and says: "O Lord! O Lord!" Yet his food is from the unlawful, his drink is from the unlawful, his clothing is from the unlawful, and he was nourished by the unlawful. So how can that be accepted?'"

“Whoever is given food by Allah, let him say: Allahumma barik lana fihi wa arzuqna khairan minhu (O Allah, bless it for us and provide us with something better than it). And whoever is given milk to drink by Allah, let him say: Allahumma barik lana fihi wa zidna minhu (O Allah, bless it for us and give us more of it). For I do not know of any food or drink that suffices, apart from milk.”
