Javed Chaaudry recounts a conversation he had with Mumtaz Mufti in which he asked him about a fairly well known contemporary personality and whether he was a buzurg. Muftiji replied that in his view this person was not a buzurg because he doesn’t meet the “criteria” for buzugi which is:
2- Minimising interaction in the affairs of the world (dunya)
3- Anonimity, shunning fame
needless to add Muftiji was quite right.
