Many are skeptic about miracles, supernatural, ‘karamat of buzurgs and aulias’, mythology, legendary ‘waqeat’ unbelievable tales (listen to Maulana Tariq Jameel), but they are considered importantly religious by Moulvi Muslims. They are taken as sacred, telling truth, but not believing in them is being disrespectful to Islam. But there are dissenters that consider the journey of Meraj contradict law of nature, intellect, that do not fit the framework of physical experience of human reality.
So should metaphysics, religion testaments be framed according to human cognition and his physical understanding alone? In biblical story, by accepting God’s command, did not Prophet Ibrahim agreed to kill his only son in bowing down to him? In today’s court of human reason, he would be charged for attempting to murder. But the event bypasses human understanding, its court rules, reason, logic - only to please God and become a knight of faith.
