The Eagerness of Hadhrat Umar (Radhi Allahu Anhu) and Hadhrat Mu'aadh (Radhi Allahu Anhu) to Participate in the Gatherings of Imaan

Hadhrat Abu Dharr (Radhi Allahu Anhu) reports that Hadhrat Umar (Radhi Allahu Anhu) would grab hold of the hands of one or two Sahabah (Radhi Allahu Anhu) and say, "Stand awhile with me so that we may renew our Imaan." They would then talk about ALLAH(سبحانه و تعالى‎) Hadhrat Aswad bin Hilaal reports that they were walking with Hadhrat Mu'aadh bin Jabal (Radhi Allahu Anhu) when he said to them, 
"Sit with us so that we may believe for a moment."
