Surah Al-Baqarah, ayah 133

أَمۡ كُنتُمۡ شُهَدَآءَ إِذۡ حَضَرَ يَعۡقُوبَ ٱلۡمَوۡتُ إِذۡ قَالَ لِبَنِيهِ مَا تَعۡبُدُونَ مِنۢ بَعۡدِيۖ قَالُواْ نَعۡبُدُ إِلَٰهَكَ وَإِلَٰهَ ءَابَآئِكَ إِبۡرَٰهِـۧمَ وَإِسۡمَٰعِيلَ وَإِسۡحَٰقَ إِلَٰهٗا وَٰحِدٗا وَنَحۡنُ لَهُۥ مُسۡلِمُونَ ١٣٣

Am kuntum shuhadā'a idh hadara ya'qūbal-mawtu idh qāla libanīhi mā ta'budūna mim ba'dī qālū na'budu ilāhaka wa ilāha ābā'ika ibrāhima wa ismā'īla wa ishāqa ilāhan wāhidan wanahnu lahū muslimūn

Or were you witnesses when death approached Jacob, when he said to his sons, "What will you worship after me?" They said, "We will worship your God and the God of your fathers, Abraham and Ishmael and Isaac - one God.⁴⁶ And we are Muslims [in submission] to Him."
