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 told them only what You commanded me to: “Worship God, my Lord and your Lord.” I was a witness over them during my time among them. Ever since You took my soul, You alone have been the watcher over them: You are witness to all things
"Never did I say to them aught except what You (Allâh) did command me to say: ‘Worship Allâh, my Lord and your Lord.’ And I was a witness over them while I dwelt amongst them, but when You took me up, You were the Watcher over them; and You are a Witness to all things. (This is a great admonition and warning to the Christians of the whole world).
