Al Maidah, 111 Ayah
5:111
وَإِذۡ أَوۡحَيۡتُ إِلَى ٱلۡحَوَارِيِّـۧنَ أَنۡ ءَامِنُواْ بِي وَبِرَسُولِي قَالُوٓاْ ءَامَنَّا وَٱشۡهَدۡ بِأَنَّنَا مُسۡلِمُونَ ١١١
Wa 'Idh 'Awĥaytu 'Ilá Al-Ĥawārīyīna 'An 'Āminū Bī Wa Birasūlī Qālū 'Āmannā Wa Ash/had Bi'annanā Muslimūna
And [remember] when I inspired to the disciples, "Believe in Me and in My messenger Jesus." They said, "We have believed, so bear witness that indeed we are Muslims [in submission to Allah ]."
