Ishaq in Surah Yusuf

﴿وَكَذَٰلِكَ يَجْتَبِيكَ رَبُّكَ وَيُعَلِّمُكَ مِن تَأْوِيلِ ٱلْأَحَادِيثِ وَيُتِمُّ نِعْمَتَهُۥ عَلَيْكَ وَعَلَىٰٓ ءَالِ يَعْقُوبَ كَمَآ أَتَمَّهَا عَلَىٰٓ أَبَوَيْكَ مِن قَبْلُ إِبْرَٰهِيمَ وَإِسْحَـٰقَ ۚ إِنَّ رَبَّكَ عَلِيمٌ حَكِيمٌ ٦﴾

(6) And thus will your Lord choose you and teach you the interpretation of narratives [i.e., events or dreams] and complete His favor upon you and upon the family of Jacob, as He completed it upon your fathers before, Abraham and Isaac. Indeed, your Lord is Knowing and Wise."

﴿وَٱتَّبَعْتُ مِلَّةَ ءَابَآءِىٓ إِبْرَٰهِيمَ وَإِسْحَـٰقَ وَيَعْقُوبَ ۚ مَا كَانَ لَنَآ أَن نُّشْرِكَ بِٱللَّهِ مِن شَىْءٍ ۚ ذَٰلِكَ مِن فَضْلِ ٱللَّهِ عَلَيْنَا وَعَلَى ٱلنَّاسِ وَلَـٰكِنَّ أَكْثَرَ ٱلنَّاسِ لَا يَشْكُرُونَ ٣٨﴾

(38) And I have followed the religion of my fathers, Abraham, Isaac and Jacob. And it was not for us to associate anything with Allāh. That is from the favor of Allāh upon us and upon the people, but most of the people are not grateful.
