When he admonished them with what he mentioned about the state of the village and what it was given due to its disbelief and bad deeds, he connected that with the conjunction in his saying 'So eat...' to deter them from the actions of ignorance and their corrupt beliefs that they were upon. He commanded them to eat what Allah has provided them of the pure and lawful, and to give thanks for His blessings in that. He said, 'If you truly worship Him,' meaning you obey. Or if your claim is correct that you worship Allah by worshiping the idols, for they are your intercessors with Him. Then he enumerated the prohibitions of Allah and forbade them from declaring them unlawful or lawful based on their desires and ignorance, without following what Allah has legislated through the tongues of His prophets.
