Sura Āl-ʿImrān 3:44

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

dhālika min anbāʾi l-ghaybi nūḥīhi ilayka wa-mā kunta ladayhim idh yulqūna aqlāmahum ayyuhum yakfulu maryama wa-mā kunta ladayhim idh yakhtaṣimūna

This is part of the tidings of the things unseen, which We reveal unto thee (O Messenger!) by inspiration: Thou wast not with them when they cast lots with arrows, as to which of them should be charged with the care of Mary: Nor wast thou with them when they disputed (the point).
