SHAFAQNA – Ayah 51 of Surah Al-Momenoon says: O’ prophets, eat clean food and do good deeds, I am aware of all you do. Ayah 172 of Surah Al-Baqarah says: O’ believers, eat of clean food We have provided for you and thank Allah (SWT) if you worship God.
Therefore if we expect after eating dubious food, do good deeds, is an unacceptable expectation. With Haram food, God cannot be worshipped. Totally clean and Halal food has a significant role because food will transfer into thought; God said to the prophets and to the people to watch what you eat.
