Obey God and obey the Messenger-Allah we never see, the Rasool has departed. So, Allah & Rasool represent the Central Authority of an Islamic State. Sir Syed, Mullah Abul Kalam Azad and even Mullah Maududi agree with this explanation.
5:92 Obey God and obey the Messenger, and beware if you turn back. Know that Our Messenger’s duty is just to convey the Message clearly.
5:93 Those who have chosen to believe and do works beneficial to the society, bear no guilt for whatever they partake (of the lawful), as long as they live upright and continue to believe, and grow ever in righteousness, and continue with their good works benefiting others. Remember that God loves the benefactors of humanity. [Ta’m, beyond eating and drinking, includes enjoying God’s bounties in all forms]
