Al-Baqarah - 2:133

أَمْ كُنتُمْ شُهَدَاء إِذْ حَضَرَ يَعْقُوبَ الْمَوْتُ إِذْ قَالَ لِبَنِيهِ مَا تَعْبُدُونَ مِن بَعْدِي قَالُواْ نَعْبُدُ إِلَـهَكَ وَإِلَـهَ آبَائِكَ إِبْرَاهِيمَ وَإِسْمَاعِيلَ وَإِسْحَاقَ إِلَـهًا وَاحِدًا وَنَحْنُ لَهُ مُسْلِمُونَ
[2:133]
Nay! were you witnesses when death visited Yaqoub, when he said to his sons: What will you serve after me? They said: We will serve your god and the god of your fathers, Ibrahim and Ismail and Ishaq, one Allah only, and to Him do we submit.
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)."
Or were ye present when death came to Jacob, when he said unto his sons: What will ye worship after me? They said: We shall worship thy god, the god of thy fathers, Abraham and Ishmael and Isaac, One Allah, and unto Him we have surrendered.
