﴿ وَكُلُوا۟ مِمَّا رَزَقَكُمُ ٱللَّهُ حَلَٰلًۭا طَيِّبًۭا ۚ وَٱتَّقُوا۟ ٱللَّهَ ٱلَّذِىٓ أَنتُم بِهِۦ مُؤْمِنُونَ ﴾

“Thus, partake of the lawful, good things which God grants you as sustenance, and be conscious of God, in whom you believe.”

And eat of the lawful and good food which God has provided you halālan tayyiban ‘lawful and good food’ is the direct object and the preceding genitive construction mimmā ‘of … which’ is a circumstantial qualifier connected to the former; and fear God in Whom you are believers.
