﴿ ذَٰلِكَ مِنْ أَنۢبَآءِ ٱلْغَيْبِ نُوحِيهِ إِلَيْكَ ۖ وَمَا كُنتَ لَدَيْهِمْ إِذْ أَجْمَعُوٓا۟ أَمْرَهُمْ وَهُمْ يَمْكُرُونَ ﴾

“THIS ACCOUNT of something that was beyond the reach of thy perception We [now] reveal unto thee, [O Prophet:] for thou wert not with Joseph's brothers when they resolved upon what they were going to do and wove their schemes [against him].”

(This) that which I mentioned to you, O Muhammad, of the story of Joseph and his brothers (is of the tidings of the Unseen) of the events which were hidden from you (which We inspire in thee (Muhammad)) with which We send Gabriel to you. (Thou wast not present with them when they bed their plan) when they agreed to throw Joseph in the well (and they were scheming) they were intending by this the peril of Joseph.
