أَمْ كُنتُمْ شُهَدَآءَ إِذْ حَضَرَ يَعْقُوبَ ٱلْمَوْتُ إِذْ قَالَ لِبَنِيهِ مَا تَعْبُدُونَ مِنۢ بَعْدِى قَالُوا۟ نَعْبُدُ إِلَـٰهَكَ وَإِلَـٰهَ ءَابَآئِكَ إِبْرَٰهِـۧمَ وَإِسْمَـٰعِيلَ وَإِسْحَـٰقَ إِلَـٰهًۭا وَٰحِدًۭا وَنَحْنُ لَهُۥ مُسْلِمُونَ

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. And we are Muslims [in submission] to Him."

— Al-Baqarah 2:133
