Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) said: "I have seen us at a time when no one stayed away from the prayer except a hypocrite whose hypocrisy was known, or a sick person; and even the sick person would come to the prayer walking, supported between two men."
And he said: "Indeed the Messenger of Allah (peace and blessings be upon him) taught us the ways of guidance, and among the ways of guidance is to pray in the mosque in which the call (adhan) is made."
