Sufism doesnt derive from hinduism.
Most of the internet junkies who are masters at digging out links to back up their claims dont understand that There is information which is not available on the internet for certain things unfortunately.and what is present is often misinterpreted while the other information has sometimes anti-islam hand at its back.
Here is something which most people dont know.
When a Wali-ALLAH(Hazrat Khuwaja Moinuddin Chishti Ajmeri) was sent to India with the mission of spreading Islam here, he studied Hindu ways first.He studied them to sort of give them an alternative for their hindu ways and then shift them towards Islam.In short, he was successful in this endeavour and many hindus became muslims.
Just a few examples:
1.A part of population in India worshipped fire/sun,so he used Chiragh(lamp).
2.The long hanging bell used in mandir(temples) by Hindus.A bell was hung outside his Hujra(a place where he sits) when he would do chilla for the needy ones to come and pull the cord three times.Since he couldnt attend to anyone so he told his disciples that by ringing the bell the wish of the affected person will reach ALLAH’s throne.
3.The smoke(dhooni) used by Hindus in their temples.I dont know whats that for really but its used to ward of spirits(jinns) in Roohaniat. But thats not the only way.Sprinkling water is also done.There are many other ways also.
