Good and Halal Food is a Rules in Accepting Doa

"O messengers, eat from the good foods and work righteousness. Indeed, I, of what you do, am Knowing (Al-Mukminun: 51)." He also said, " O you who have believed, eat from the good things which We have provided for you and be grateful to Allah if it is [indeed] Him that you worship (Al-Baqarah: 172)."

Rasulullah saw said, "Allah is Good and only accepts that which is good…” and he mentioned a man who has been traveling for a long time and is unkempt and covered with dust, and he raises his hands to the heavens (and says), “O Lord, O Lord,” when his food is haraam, his drink is haraam, his clothes are haraam, and he is nourished with haraam, so how can he receive any response?" (Narrated by Muslim, no. 1015).
