Muhaddith-e-Deccan Abul Hasanaat Hadhrat Syed Abdullah Shah Naqshbandi Mujaddidi Qadri (May Allah shower His mercy on him) writes about the blessings gained from the mention of the miracles, the incidents and anecdotes of the saints:
Translation: The way abundance of Dhikr and profuse recitation of the Holy Quran is necessary for the seeker (Salik), in the same way it is necessary to keep going through the incidents of the saints! People asked Hadhrat Junaid Baghdadi (May Allah shower His mercy on him) as to what is the benefit to the seeker from the incidents and traditions of the saints. He replied: By the mention of the friends of Almighty Allah, the heart of the seeker is strengthened and by the blessings of the mention of the saints, the mercy of Allah descends.
Hadhrat Abu ‘Ali Daqqaq (May Allah shower His mercy on him) says: There are 2 benefits on listening to the incidents and anecdotes of the men of Allah. One, that if the seeker desires (the pleasure and approval) of Almighty Allah, his (or her) zeal and strength is further increased. Secondly, if a person is proud, then his (or her) pride is lessened and essentially wiped out. He sees his blameworthy attributes as blameworthy and he is also made aware of the sightlessness of his inward aspect as well. (Mawaaiz-e-Hasana, Vol. 1, Pg. No. 132)
