ما قُلتُ لَهُم إِلّا ما أَمَرتَني بِهِ أَنِ اعبُدُوا اللَّهَ رَبّي وَرَبَّكُم ۚ وَكُنتُ عَلَيهِم شَهيدًا ما دُمتُ فيهِم ۖ فَلَمّا تَوَفَّيتَني كُنتَ أَنتَ الرَّقيبَ عَلَيهِم ۚ وَأَنتَ عَلىٰ كُلِّ شَيءٍ شَهيدٌ

I said not to them except what You commanded me - to worship Allah, my Lord and your Lord. And I was a witness over them as long as I was among them; but when You took me up, You were the Observer over them, and You are, over all things, Witness.
