﴿ وَلَئِنْ أَطَعْتُم بَشَرًۭا مِّثْلَكُمْ إِنَّكُمْ إِذًۭا لَّخَٰسِرُونَ ﴾
“and, indeed, if you pay heed to a mortal like yourselves, you will surely be the losers!”
And by God if you obey a human being like yourselves this clause contains both an oath and a conditional; the response belongs to the former the oath which at the same time suffices in place of a response for the latter the conditional you will surely then that is should you obey them be losers you will have been duped.
