A seeker inquired,

‘Is keeping a fist length beard an absolute requirement (I do have a beard but not fist length)?

Is keeping your pants (or shalwar) above the ankle another absolute requirement?

Following answer was given by Ashrafiya,

Tasawwuf deals with the ailments of the heart which are the root cause of all sins (actions against Sunna are sins). That is the reason most Shyukh do not instruct their disciples on fiqhi issues and direct them to muftis.

In simple words, it not a rerequirement to have these prior to becoming a murid/talib e islah. When the disease causing this will be treated there will be no resistance in doing the Sunna acts.
