فَلَمَّا ذَهَبُواْ بِهِ وَأَجْمَعُواْ أَن يَجْعَلُوهُ فِي غَيَابَةِ الْجُبِّ وَأَوْحَيْنَا إِلَيْهِ لَتُنَبِّئَنَّهُم بِأَمْرِهِمْ هَـذَا وَهُمْ لاَ يَشْعُرُونَ
[12:15]
So when they had gone off with him and agreed that they should put him down at the bottom of the pit, and We revealed to him: You will most certainly inform them of this their affair while they do not perceive.
So they did take him away, and they all agreed to throw him down to the bottom of the well: and We put into his heart (this Message): 'Of a surety thou shalt (one day) tell them the truth of this their affair while they know (thee) not'
Then, when they led him off, and were of one mind that they should place him in the depth of the pit, We inspired in him: Thou wilt tell them of this deed of theirs when they know (thee) not.
