Dear Beyond Tradition,
As-salamu alaykum
Please kindly see my responses in brown italics to your questions below:
1 . Prophet Yusuf did know the future of his ministry ---- Quran's perspective no one can know the future .
No one knows of a future event unless God informs a chosen servant of an event through a dream, revelations (Scripture) or by direct communication (as was the case with Prophet Moses). Only God knows the future and only He can part that information to whom He pleases.
It is clear from the Quran that Prophet Joseph did have the ability to interpret dreams which from the narratives that are presented in the Quran, were of future events. This was a gift that God had endowed upon Prophet Joseph. However, this does not mean that Prophet Joseph knew everything about the future of his ministry or was able to predict the future at will.
2. He could tell the true meaning of dream of the people of his ministry . ---- In Quran's perspective is it true ?
Yes, Prophet Joseph could interpret dreams correctly and not only for the people of his ministry.
3. Also a lady ( Jolekha ) fallen in love with him ( Prophet Yusuf) --- In Quran's perspective is it true ?
There is mention of a woman (The wife of the Aziz) that was awe-stricken with Joseph. The exclamation from the women of the city does appear to indicate that she was smitten with love (shaghafaha hubban – 12:30). However, there is no mention of the name ‘Jolekha’ or any name of the wife of the Aziz.
4. It is also belief that Prophet Yusuf has recovered her blindness and returned her young age from old age .
There is no evidence of this from the Quran.
I hope this helps, God willing
Joseph
