Surah Al-Mai'dah (The Spread Table), Verse 117

مَا قُلْتُ لَهُمْ اِلَّا مَاۤ اَمَرْتَنِیْ بِهٖۤ اَنِ اعْبُدُوا اللّٰهَ رَبِّیْ وَرَبَّكُمْ وَكُنْتُ عَلَیْهِمْ شَهِیْدًا مَّا دُمْتُ فِیْهِمْ فَلَمَّا تَوَفَّیْتَنِیْ كُنْتَ اَنْتَ الرَّقِیْبَ عَلَیْهِمْ وَاَنْتَ عَلٰی كُلِّ شَیْءٍ شَهِیْدٌ ۟

Maa qultu lahum illaa maaa amartanee bihee ani'budul laaha Rabbeee wa Rabbakum; wa kuntu 'alaihim shaheedam maa dumtu feehim falammaa tawaffaitanee kunta Antar Raqeeba 'alaihim; wa Anta 'alaa kulli shai'in Shaheed

“"Never said I to them aught except what Thou didst command me to say, to wit, 'worship Allah, my Lord and your Lord'; and I was a witness over them whilst I dwelt amongst them; when Thou didst take me up Thou wast the Watcher over them, and Thou art a witness to all things.”
