Allah gave Ibrahim Ishaq and Yaqub Allah, the Exalted, says;فَلَمَّا اعْتَزَلَهُمْ وَمَا يَعْبُدُونَ مِن دُونِ اللَّهِ وَهَبْنَا لَهُ إِسْحَقَ وَيَعْقُوبَSo when he had turned away from them and from those whom they worshipped besides Allah, We gave him Ishaq and Ya`qub, and each one of them We made a Prophet. Allah, the Exalted, says that when the Friend of Allah (Ibrahim) withdrew from his father and his people for the sake of Allah, Allah gave him in exchange those who were better than them. He gave him Ishaq (Isaac) and Yaqub (Jacob), meaning his son, Ishaq, and Ishaq's son, Yaqub. This is as Allah said in another Ayah,وَيَعْقُوبَ نَافِلَةًand Yaqub, a grandson. (21:72)Also, Allah says,وَمِن وَرَاءِ إِسْحَـقَ يَعْقُوبَand after Ishaq, of Yaqub. (11:71)There is no difference of opinion about Ishaq being the father of Yaqub. This is what is recorded in the Qur'an in Surah Al-Baqarah.أَمْ كُنتُمْ شُهَدَاءَ إِذْ حَضَرَ يَعْقُوبَ الْمَوْتُ إِذْ قَالَ لِبَنِيهِ مَا تَعْبُدُونَ مِن بَعْدِى قَالُواْ نَعْبُدُ إِلَـهَكَ وَإِلَـهَ ابَأيِكَ إِبْرَهِيمَ وَإِسْمَـعِيلَ وَإِسْحَـقَOr were you witnesses when death approached Yaqub When he said unto his sons, "What will you worship after me!"They said, "We shall worship your God the God of your fathers, Ibrahim, Ismail and Ishaq." (2:133)Allah only mentioned Ishaq and Yaqub here to show that He made Prophets from among his descendants and successors in order to give him relief and happiness in his life.This is why Allah says,وَكُلًّ جَعَلْنَا نَبِيًّاand each one of them We made a Prophet.If Yaqub had not become a Prophet in the lifetime of Ibrahim, then Allah would not have limited the promise of Prophethood to him, but He would have mentioned his son Yusuf as well. For verily, Yusuf was also a Prophet, just as the Messenger of Allah said in a Hadith whose authenticity is agreed upon, when he was asked who was the best of people.He said,يُوسُفُ نَبِيُّ اللهِ ابْنُ يَعْقُوبَ نَبِيِّ اللهِ ابْنِ إِسْحَاقَ نَبِيِّ اللهِ ابْنِ إِبْرَاهِيمَ خَلِيلِ اللهThe Prophet of Allah, Yusuf, the son of the Prophet of Allah Yaqub, the son of the Prophet of Allah Ishaq, the son of the Friend of Allah Ibrahim.In another wording of this Hadith, he said,إِنَّ الْكَرِيمَ ابْنَ الْكَرِيمِ ابْنِ الْكَرِيمِ ابْنِ الْكَرِيمِ يُوسُفَ بْنَ يَعْقُوبَ بْنِ إِسْحَاقَ بْنِ إِبْرَاهِيمVerily, the noble one is the son of the noble one, who is the son of the noble one, who is the son of the noble one. That is Yusuf, the son of Yaqub, the son of Ishaq, the son of Ibrahim.Concerning Allah's statement,وَوَهَبْنَا لَهُم مِّن رَّحْمَتِنَا وَجَعَلْنَا لَهُمْ لِسَانَ صِدْقٍ عَلِيًّا
