As-salamu 'Alaykum Wa Rahmatullahi Wa Barakatuhu,
I was wondering what are the different masteries that an 'Alim can go thru after going completing the 'Alimiyyah course in various Dar-ul-Ulooms? I have been contemplating Iftaa', Hadith, Tibb, Tafsir, History, and Arabic Language. I am sure there are much more. And which places are the best to go and study these masteries?
