أطيب طيب this is a homonym and read Teeb as well as Tayyib. Tayyib means nice, pure, refined; and aTyab is the superlative of Tayyib. Teeb means perfume and it is a noun. aTyabu'l bayan means: classy and pure speech in the refutation of tafwiyatu'l eeman. [it is a subtle dig on the impure speech of ismayil.]
pardon my arabic, can it be aTeeb al-bayan? --- taqwiyyat means strengthening. tafwiyyat means destroying/killing. so ismayil's book is tafwiyyat al-iman. he himself has said that in his filthy book, he has labelled those acts major shirk that are actually minor shirk. who has given the father of wahabism this right to change such rulings? it is true what mawlana sa'eed as'ad said years ago: wahabi's will drink poison but will not debate on the kufriyyat of ismayil with him because they too know that their molwi has committed kufr.
aţyab al-bayān a classical refutation by Mawlānā Náīm Uddīn Murādabādī raĥimahullāh of the infamous book taqwiyyat al-īmān which is appropriately called tafwiyyat al-īmān.
