Can we make any pledge (Bayath) to any Sheiks or Walis?

All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.

The answer for this question depends on the kind and the subject on which the pledge is made.

If the pledge is made to cooperate in righteousness and to fear Allah, then it is permissible, and fulfilling such a pledge becomes an obligation on everyone who has accepted it.

If the pledge is made on that which is forbidden in the Sharee’ah, particularly the pledge to Shaykhs of at-Tareeqah (Sufism) to abide by their Tareeqah which contain so many deviations and innovations, then it is forbidden and one should avoid enrolling himself into such pledges.

For more benefit on Sufism, please refer to Fataawa 82017, 31043, 31031, 83615 and 29243.

Allah knows best.
