I hope I'm allowed to ask as it's not fiqh.
I've heard there's lots of bidah shirk kufr associated with sufis thats why I was hesitant to learn about it, but learnt there's both good and bad, take the good and leave the bad. Just happen to listen to the series on tasawuf by respected Mufti Abdur Rahman Ibn Yusuf, before listening to it I was afraid I might came across something which cause doubts but everything was comprehensible. Alhamdulillah.
I also read few articles here and there but I dunno much, I want to know more pls gimme link to authentic books, audio, video, or point me to any discussion around which help understand tassawuf.
Also, I've questions, Tijani Tariqah is considered deviant by Respected Ahmed sadiq Desai, here on pg. no. 7 Do all sunnis consider them deviants or is this just Mufti A.S. Desai?
what's exactly the spiritual state or haal or different world?
Jazakumullahu khairan.
