From Abu Al-Dardaa (may Allah be pleased with him), who said: The Prophet (SAW) said: Shall I not inform you all of the best of your deeds, the purest of them in the sight of your Sovereign, the highest of them in your standing, better for you than spending gold and silver, and better for you than meeting your enemy and striking off their heads and them striking off your heads? The people said: Yes indeed! He said: Remembrance [dhikr] of Allah Most High.
