Ghayb? So the One Who imparts knows it and the one who gains knows it. In Ayah 24 of Surah At-Takweer, part 30, Allah عَزَّوَجَلَّ has stated about the unseen knowledge of the Beloved Rasool صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم:

وَ مَا هُوَ عَلَى الْغَیْبِ بِضَنِیْنٍۚ(۲۴)

Translation from Kanz-ul-Iman: And he (the Rasool) is not a miser to disclosethe unseen. (Part 30, Surah At-Takweer, Ayah 24)

Regarding the blessed Ayah, it is stated in Tafseer Khaazin: This blessed Ayah implies that when the Beloved Rasool صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم attains knowledge of the Ghayb, he صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم does not become stingy in this regard, but rather he صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم imparts it to you. (Tafseer Khaazin, vol. 4, pp. 357)

From this blessed Ayah and its Tafseer it has become obvious that the Beloved Rasool صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم imparts the knowledge of Ghayb to people and obviously the one who himself knows will tell.

Scholarly status of Imam-e-A’zam in the sight of Beloved Rasool

Giving news of one knowledge of Ghayb, the Beloved Rasool صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم has stated: ‘لَوۡ كَانَ الۡعِلۡمُ بِالثُّرَيَّا لَتَنَاوَلَهٗ اُنَاسٌ مِّنۡ اَبۡنَاءِ فَارس’ If knowledge were suspended in the Surayya [the Pleiades], some people from the descendants of Persia would get it even from there. (Musnad Ahmad, vol. 3, pp. 154, Hadees 7955)

Sayyiduna Imam Ibn Hajar Makki رَحْمَةُ اللهِ تَعَالٰی عَلَيْه has stated: This sacred Hadees refers to the blessed personality of Imam-e-A’zam Abu Hanifah رَحْمَةُ اللهِ تَعَالٰی عَلَيْه and there is no doubt in this fact as in his era, no one from people of Persia attained the status regarding knowledge that he had, or rather no one even attained the scholarly status that his students had. It also contains the clear miracle of the Beloved Rasool صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم that he صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم gave the news of Ghayb, that is, he stated what was going to happen.
