An-Nahl 16:94

Do not take your oaths as a means of deceit between yourselves, lest some feet will slip after they have been firm[60], and you will taste the evil consequences of preventing people from the way of Allah, and for you there will be a great punishment.

[60] i.e., after their feet became firm in Islam.

And do not take your oaths as [means of] deceit between you, lest a foot slip after it was [once] firm, and you would taste evil [in this world] for what [people] you diverted from the way of Allāh,[714] and you would have [in the Hereafter] a great punishment.

[714] Referring to those who would be dissuaded from Islām as a result of a Muslim's deceit and treachery.

94. And make not your oaths a means of deception among yourselves, lest a foot should slip after being firmly planted, and you may have to taste the evil (punishment in this world) of having hindered (men) from the Path of Allâh (i.e. Belief in the Oneness of Allâh and His Messenger, Muhammad صلى الله عليه و سلم), and yours will be a great torment (i.e. the Fire of Hell in the Hereafter).

Make not your oaths a deceit between you, lest a foot should slip after being firmly planted and ye should taste evil forasmuch as ye debarred (men) from the way of Allah, and yours should be an awful doom.
