Sayyidi wa sanadi Shaikh Mufti Mohammad Taqi Usmani (Allah preserve him) said,
‘Sit in solitude. Close your eyes. Contemplate (do muraqaba). Repeatedly remind yourself either by saying it or thinking that, ‘I am in front of Allah’, ‘I am in front of Allah! Allah is watching me! Allah is watching me! I am in front of Allah! Allah is watching me’
Do this daily for some (fixed) duration of time.
As a result of this activity, by the kind bestowal of Allah, this awareness will gradually and progressively increase.
This contemplation is known as muraqaba e Ihsan.
Allah provides assistance to the one who does this activity (punctually). A awareness develops in this individual prior to all actions and verbal sayings that makes him ponder about the permissibility and accountability (in front of Allah) about that actions or sayings he is going to do.
This is a recommendable state.
It changes the heedless lifestyle into a cautious and caring one.’
