ذَٰلِكَ مِنْ أَنۢبَآءِ ٱلْغَيْبِ نُوحِيهِ إِلَيْكَ ۚ وَمَا كُنتَ لَدَيْهِمْ إِذْ يُلْقُونَ أَقْلَـٰمَهُمْ أَيُّهُمْ يَكْفُلُ مَرْيَمَ وَمَا كُنتَ لَدَيْهِمْ إِذْ يَخْتَصِمُونَ

This is an account of things beyond your knowledge that We reveal to you [Muhammad]: you were not present among them when they cast lots to see which of them should take charge of Mary, you were not present with them when they argued [about her].
This is a part of the news of the Ghaib (unseen, i.e. the news of the past nations of which you have no knowledge) which We reveal to you (O Muhammad صلى الله عليه وسلم). You were not with them, when they cast lots with their pens as to which of them should be charged with the care of Maryam (Mary); nor were you with them when they disputed.
