The Importance of Zikr

Hazrat Abdullah bin Busr Radhiyallahu anhu narrates that a Sahaabi once asked Nabi Sallallahu alaihi wasallam:

“O Rasool of Allah! (I know that) the commandments of the Shari’at are many, tell me the one that I may practice diligently.”

Nabi Sallallahu alaihi wasallam replied:

“Keep your tongue moist (busy/moving) with the Zikr of Allah.”
