Assalam un Alaikum,
INSANE KAMIL is someone with no sins and faults; with perfect personality, not fighting or arguing or telling lies, not capturing other's rights, showing contentment on what God has given him and helping the poor and needy, respecting his elders, praying to Allah for Allah's ownself not for show-off or RIYA, loving the children and the animals, dealing with his creatures with care and love, not performing bad actions with his eyes, nose, mouth, ears, tongue, hands or legs or any parts of the body, not teasing people...................
If you want more about it study the life of Maula Ali A.S. He is the perfect being - the INSANE KAMIL, who cries during night and shares with his Allah and smiles to the people who even smiles when someone is supposed to fight with him.
For more and more study the book of Shaheed Murtaza Mutahhari by the name of ''INSANE KAMIL''
Iltamas-e-Duaa
with best regards
Yasmeen Hussaini.
