أَمْ كُنتُمْ شُهَدَآءَ إِذْ حَضَرَ يَعْقُوبَ ٱلْمَوْتُ إِذْ قَالَ لِبَنِيهِ مَا تَعْبُدُونَ مِنۢ بَعْدِى قَالُوا۟ نَعْبُدُ إِلَٰهَكَ وَإِلَٰهَ ءَابَآئِكَ إِبْرَٰهِـۧمَ وَإِسْمَٰعِيلَ وَإِسْحَٰقَ إِلَٰهًا وَٰحِدًا وَنَحْنُ لَهُۥ مُسْلِمُونَ ١٣٣
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."
Explanation: Al-Mukhtasar
Were you present at the time of Jacob’s death, when he asked his sons what they would worship after he had died? They replied to him, saying that they would worship Allah, the Lord of his forefathers – Abraham, Ishmael and Isaac – namely, the One Allah without partners; and they said that they surrendered in devotion to Him alone and were bound to Him.
