Steer well clear of this guy. He is the founder of jamaat e islami movement which has its roots in disparaging the Prophets of Allah. Just do a search on this movement and you will find numerous fatwas by sunni ulema on this group.
Can someone clarify what his maslak was? Online I can see he approved of some sufism and rejected others. I have a book by him on marriage and divorce in islam. Although it's fiqh. I've noticed how salafi or deobandi hanfia have they're tweak on fiqh. Thanks
