Qur'an 5:117

مَا قُلْتُ لَهُمْ إِلَّا مَآ أَمَرْتَنِى بِهِۦٓ أَنِ ٱعْبُدُوا۟ ٱللَّهَ رَبِّى وَرَبَّكُمْ ۚ وَكُنتُ عَلَيْهِمْ شَهِيدًا مَّا دُمْتُ فِيهِمْ ۖ فَلَمَّا تَوَفَّيْتَنِى كُنتَ أَنتَ ٱلرَّقِيبَ عَلَيْهِمْ ۚ وَأَنتَ عَلَىٰ كُلِّ شَىْءٍ شَهِيدٌ

I spake unto them only that which Thou commandedst me, (saying): Worship Allah, my Lord and your Lord. I was a witness of them while I dwelt among them, and when Thou tookest me Thou wast the Watcher over them. Thou art Witness over all things.
