Q 12:6

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

Translations

And thus will your Lord choose you and teach you the interpretation of narratives 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."

Sahih International · EN

Ainsi ton Seigneur te choisira et t'enseignera l'interprétation des rêves, et Il parfera Son bienfait sur toi et sur la famille de Jacob, tout comme Il l'a parfait auparavant sur tes deux ancêtres, Abraham et Isaac, car ton Seigneur est Omniscient et Sage.

Tafsir

Just as you have seen that dream, your Lord will choose you, O Joseph, and teach you the interpretation of dreams; and He will perfect His favour on you by giving you prophethood, as well as kingdom, just as He completed His blessing on your two forefathers before you, Abraham and Isaac, with the favours of this world and the Afterlife that He blessed them with. Your Lord is One Who knows His creation and Who is Wise in His planning.

Read Ibn Kathir (Ibn Kathir (abridged, English))

"Thus will your Lord choose you and teach you the interpretation of dreams (and other things) and perfect His favor on you and on the offspring of Ya'qub, as He perfected it on your fathers, Ibrahim and Ishaq aforetime! Verily, your Lord is All-Knowing, All-Wise. (6) Interpretation of Yusuf's Vision Allah says that Ya'qub said to his son Yusuf, 'Just as Allah chose you to see the eleven stars, the sun and the moon prostrate before you in a vision, وَكَذَٰلِكَ يَجْتَبِيكَ رَبُّكَ (Thus will your Lord choose you) designate and assign you to be a Prophet from Him, وَيُعَلِّمُكَ مِن تَأْوِيلِ الْأَحَادِيثِ (and teach you the interpretation of Ahadith).' Mujahid and several other scholars said that this part of the Ayah is in reference to the interpreting of dreams. He said next, وَيُتِمُّ نِعْمَتَهُ عَلَيْكَ (and perfect His favor on you), 'by His Message and revelation to you.' This is why Ya'qub said afterwards, كَمَا أَتَمَّهَا عَلَىٰ أَبَوَيْكَ مِن قَبْلُ إِبْرَاهِيمَ (as He perfected it aforetime on your fathers, Ibrahim...), Allah's intimate friend, وَإِسْحَاقَ (and Ishaq), Ibrahim's son, إِنَّ رَبَّكَ عَلِيمٌ حَكِيمٌ (Verily, your Lord is All-Knowing, All-Wise.) Allah knows best whom to chose for His Messages.
