ذَٰلِكَ مِنْ أَنۢبَآءِ ٱلْغَيْبِ نُوحِيهِ إِلَيْكَ ۖ وَمَا كُنتَ لَدَيْهِمْ إِذْ أَجْمَعُوٓا۟ أَمْرَهُمْ وَهُمْ يَمْكُرُونَ
Zaalika min ambaaa'il ghaibi nooheehi ilaika wa maa kunta ladaihim iz ajma'ooo amrahum wa hum yamkuroon
This account is part of what was beyond your knowledge [Muhammad]. We revealed it to you: you were not present with Joseph’s brothers when they made their treacherous plans.
That is from the tidings of the unseen which we reveal to you. You were not with them when they settled on their plan and schemed together.
