ذَٰلِكَ مِنْ أَنۢبَآءِ ٱلْغَيْبِ نُوحِيهِ إِلَيْكَ ۚ وَمَا كُنتَ لَدَيْهِمْ إِذْ يُلْقُونَ أَقْلَٰمَهُمْ أَيُّهُمْ يَكْفُلُ مَرْيَمَ وَمَا كُنتَ لَدَيْهِمْ إِذْ يَخْتَصِمُونَ
This is of the tidings of things hidden. We reveal it unto thee (Muhammad). Thou wast not present with them when they threw their pens (to know) which of them should be the guardian of Mary, nor wast thou present with them when they quarrelled (thereupon).
Surah Aal-i-Imraan(3:44)
