So when they took him [out] and agreed to put him into (12:15)

Almuntakhab Fi Tafsir Alquran Alkarim

And they took him and went away, and agreed among themselves, and were united in thought, to place him at the bottom of the well -said to have been dry-. There and then We inspired just confidence and peace of mind to him -Yusuf- and inspired him with the feeling, thus: You shall one day inform them of the evil they had committed against you at a time when they fail to recognize you nor perceive ever they shall see you again

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(12:15) When, after persisting like this, they took him away with them, and decided to cast him into a dark well, We revealed this to Joseph: "A time will surely come when you will admonish them about this act of theirs; now they do not comprehend its consequences. " *12

So when they took him [out] and agreed to put him into meaning

*12) The Arabic words ("they do not understand" ) may very appropriately mean three things. First, "We were comforting Joseph, and his brothers were quite unaware of this that a Revelation was being sent to him." Second, "You will Iet them know of this evil act of theirs in such circumstances that they can never even imagine you to be there." Third, "Today they are committing an evil act, but they do not know its future consequences."
There is no mention of this in the Bible and the Talmud that Allah sent a Revelation to comfort Prophet Joseph at that time of his affliction. On the contrary, the Talmud says that when he was thrown into the well, Prophet Joseph wept and cried aloud and implored his brothers for mercy, as if he was no better than any other lad of the desert, who would weep and cry if he were to be thrown into a well. But the picture the Qur'an depicts is that of a young man, who is destined to play the part of a great personality in history.

اِس طرح اصرار کر کے جب وہ اُسے لے گئے اور انہوں نے طے کر لیا کہ اسے ایک اندھے کنویں میں چھوڑ دیں، تو ہم نے یوسفؑ کو وحی کی کہ "ایک وقت آئے گا جب تو ان لوگوں کو ان کی یہ حرکت جتائے گا، یہ اپنے فعل کے نتائج سے بے خبر ہیں"
