172. In the time of the Prophet (peace be on him) no one, unless he prayed regularly, could be reckoned as belonging to the Islamic community. We know that secular associations consider the absence of any member from their meetings, without a valid excuse, a sign of lack of interest, and that in the event of continued absence, they cancel his membership. The early Islamic community did the same with those who absented themselves from congregational Prayers. In those days a person's absence from congregational Prayers was considered a clear indication of his indifference towards Islam: if he absented himself from them repeatedly he was no longer held to be a Muslim. In those days, therefore, even the worst hypocrites had to attend the five daily Prayers in the mosque. What distinguished a true believer from the hypocrite was that the former came to the mosque with devotion, fervour and eagerness, came there well before the appointed time for the Prayer, and did not rush out of the mosque as soon as the Prayer was over. In short, everything about him indicated that his heart was in the Prayer. Whereas the call to the Prayer for the hypocrite seemed like the announcement of an unavoidable calamity. When such a person set off for the mosque, he seemed to do so in spite of himself. He walked as if he were dragging the entire weight of his being. No wonder, then, that as soon as the Prayer was over, he escaped like a prisoner released from jail. His entire demeanour testified that the remembrance of God was not what he really had his heart in.
