The correct answer is option 1: Sheikh Mubarak. Abdul Fazal was the son of Sheikh Mubarak, who was a Sufi saint. A Sufi saint is a spiritual practitioner who follows the teachings of Sufism, a mystical Islamic tradition. Sufism emphasizes the inward spiritual journey and the experience of divine love and knowledge. Abdul Fazal`s father, Sheikh Mubarak, was likely an influential figure in Sufism, guiding and teaching others on their spiritual paths. It is important to note that the other options given, namely option 2 Hazarat Khwaja, option 3 Nasiruddin Chirag, and option 4 Baba Qutubuddin Bakhtiyar, are unrelated to Abdul Fazal`s lineage and should be disregarded.
