Hazrat Hanif Sahab Luharvi (DB) said that people asked my first Shaikh Mufti Mahmood-ul-Hasan Gangohi (RA) what is well being (actually Arabic-Urdu 'aafiyat). A person is in the state of well being if he has got three things. Obedience to Sunnah, normal breathing (without medical help) and a halaal diet in time. Such person should think of himself being in a state of well being and prosperity.
