Shaikh Professor Mohammad Ashraf Khan Sulemani (Allah have mercy on him) said,
‘Zikr e qalbi (the remembrance of the heart) is that at all the times, while standing, sitting, talking, trading, listening, telling, writing, reading etc. the thought that Allah is watching me prevails.
This contemplation (if it is genuinely acquired) should hold one from committing sins and make steadfast on good works.’
