Hazrat Moulana Ashraf Ali Thanwi (rahmatullahi ‘alaih) once mentioned:
People regard different things to be the sign of a person’s perfection. Some people base perfection on one’s excessive ‘ibaadah (worship), while others base perfection on one’s level of taqwa (piety and abstinence). However, according to the ‘Ulama, the person who has truly acquired perfection is he who, with possessing the qualities of perfection, always keeps his weaknesses and faults before him at all times. (Malfoozaat Hakeemul Ummat 3/321)
