Sayyidi wa sanadi Mufti Mohammad Taqi Usmani (Allah preserve him) said,
‘Leaving sinful activities is an absolute essential (fardh).
Vigilance is required for this. We do supererogatory (nafil) acts of worship with zeal and passion, but are lax in abstaining from sinful.
Our similitude is like a person trying to cool a room with air conditioning but has left the windows open. All the cool air is swept away via the windows. Moreover, hot air is entering the room from outside. How can coolness be achieved? Only when we shut the windows close air conditioning will have its effect in cooling the room.
Our windows are sight, hearing, speech and imagination abilities. Not restricting them from sinful is like keeping them open. Shut them up from all that is sinful.
Genuine effort is required in this regards.’
