When you were on the nearer side (of the valley) and they were on the farthest side, while the caravan was in a lower place than you; and if you had mutually made an appointment, you would certainly have broken away from the appointment, but-- in order that Allah might bring about a matter which was to be done, that he who would perish might perish by clear proof, and he who would live might live by clear proof; and most surely Allah is Hearing, Knowing;

So He made hypocrisy to follow as a consequence into their hearts till the day when they shall meet Him because they failed to perform towards Allah what they had promised with Him and because they told lies.

And the Shaitan shall say after the affair is decided: Surely Allah promised you the promise of truth, and I gave you promises, then failed to keep them to you, and I had no authority over you, except that I called you and you obeyed me, therefore do not blame me but blame yourselves: I cannot be your aider (now) nor can you be my aiders; surely I disbelieved in your associating me with Allah before; surely it is the unjust that shall have the painful punishment.

So we too will produce before you magic like it, therefore make between us and you an appointment, which we should not break, (neither) we nor you, (in) a central place.
