Our master Shaykh Haji Imdadullah mohajir Makki (Allah have mercy on him) instructed,
‘Avoid the companionship of,

1. One who contravenes the ruling of Shariah. 

2. One who rejects Tasawwuf. 

3. Innovator (in Religious affairs ). 

4. A Sufi who opposes the Sunna:the way of Prophet (Allah bless him & grant him peace) even though he can perform supernatural feats others can’t do or even he is able to fly in the sky.’
