With regard to “holding the hand of Saints”, a poet describes as to how Allah ta’ala opens up the road;
My journey has become easy now that the winds have changed their direction. The lamps of the road have lit up now that I have held your hand.
When one “holds the hand” of a pious person, i.e. when he surrenders himself for reformation under the guidance of a qualified spiritual mentor i.e. a Shaykh, then it becomes easy for him to conform to the Sunnah and the Shar’iah, as well as to abstain from sins.
