Al-Baqarah 2:133

أَمْ كُنتُمْ شُهَدَآءَ إِذْ حَضَرَ يَعْقُوبَ ٱلْمَوْتُ إِذْ قَالَ لِبَنِيهِ مَا تَعْبُدُونَ مِنۢ بَعْدِى قَالُوا۟ نَعْبُدُ إِلَٰهَكَ وَإِلَٰهَ ءَابَآئِكَ إِبْرَٰهِۦمَ وَإِسْمَٰعِيلَ وَإِسْحَٰقَ إِلَٰهًۭا وَٰحِدًۭا وَنَحْنُ لَهُۥ مُسْلِمُونَ

Were ye witnesses when death appeared before Jacob? Behold, he said to his sons: "What will ye worship after me?" They said: "We shall worship Thy god and the god of thy fathers, of Abraham, Isma'il and Isaac,- the one (True) Allah: To Him we bow (in Islam)."
