Abdullah bin al-Samit (may Allah have mercy on him) says: I went out to the mosque on Friday and met Abu Dharr (may Allah be pleased with him), and we were walking. When we heard the call to prayer, I walked a little faster because of the saying of Allah: "When the call is made for the prayer on Friday, then hasten to the remembrance of Allah." [Surah al-Jumu'ah: 9] Abu Dharr (may Allah be pleased with him) pulled me back so hard that I almost collided with him. Then he said: Are we not already striving?
