Surah Aali Imran (The Family of Imran), Verse 81

وَاِذْ اَخَذَ اللّٰهُ مِیْثَاقَ النَّبِیّٖنَ لَمَاۤ اٰتَیْتُكُمْ مِّنْ كِتٰبٍ وَّحِكْمَةٍ ثُمَّ جَآءَكُمْ رَسُوْلٌ مُّصَدِّقٌ لِّمَا مَعَكُمْ لَتُؤْمِنُنَّ بِهٖ وَلَتَنْصُرُنَّهٗ قَالَ ءَاَقْرَرْتُمْ وَاَخَذْتُمْ عَلٰی ذٰلِكُمْ اِصْرِیْ قَالُوْۤا اَقْرَرْنَا قَالَ فَاشْهَدُوْا وَاَنَا مَعَكُمْ مِّنَ الشّٰهِدِیْنَ ۟

Wa iz akhazal laahu meesaaqan Nabiyyeena lamaaa aataitukum min Kitaabinw wa Hikmatin summa jaaa'akum Rasoolum musaddiqul limaa ma'akum latu'minunna bihee wa latansurunnah; qaala a'aqrartum wa akhaztum alaa zaalikum isree qaalooo aqrarnaa; qaala fashhadoo wa ana ma'akum minash shaahideen

“Behold! Allah took the covenant of the prophets, saying: "I give you a Book and Wisdom; then comes to you a messenger, confirming what is with you; do ye believe in him and render him help." Allah said: "Do ye agree, and take this my Covenant as binding on you?" They said: "We agree." He said: "Then bear witness, and I am with you among the witnesses."”
