Heel

And thus We have made you a median [i.e., just] community that you will be witnesses over the people and the Messenger will be a witness over you. And We did not make the qiblah which you used to face except that We might make evident who would follow the Messenger from who would turn back on his heels.¹ And indeed, it is difficult except for those whom Allāh has guided. And never would Allāh have caused you to lose your faith [i.e., your previous prayers]. Indeed Allāh is, to the people, Kind and Merciful.

Muḥammad is not but a messenger. [Other] messengers have passed on before him. So if he was to die or be killed, would you turn back on your heels [to unbelief]? And he who turns back on his heels will never harm Allāh at all; but Allāh will reward the grateful.

O you who have believed, if you obey those who disbelieve, they will turn you back on your heels, and you will [then] become losers.

Say, "Shall we invoke¹ instead of Allāh that which neither benefits us nor harms us and be turned back on our heels after Allāh has guided us? [We would then be] like one whom the devils enticed [to wander] upon the earth confused, [while] he has companions inviting him to guidance, [calling], 'Come to us.'"² Say, "Indeed, the guidance of Allāh is the [only] guidance; and we have been commanded to submit to the Lord of the worlds.

And [remember] when Satan made their deeds pleasing to them and said, "No one can overcome you today from among the people, and indeed, I am your protector." But when the two armies sighted each other, he turned on his heels and said, "Indeed, I am disassociated from you. Indeed, I see what you do not see; indeed, I fear Allāh. And Allāh is severe in penalty."

My verses had already been recited to you, but you were turning back on your heels
