The reward for an act of worship is connected to the sincerity and effort involved. The greater the effort and the greater the sincerity, the greater the reward will be. In this hadith, the Prophet highlights the virtue of walking to the mosque from far away, and the virtue of waiting to pray in the mosque with the imam. He said: “The people who will have the greatest reward for prayer are those who have to come from the furthest distance.” Then he (blessings and peace of Allah be upon him) mentioned that the reason why the reward for the prayer in this case is so great is the distance walked; in other words, the long distance and the many steps taken. That is because the hardship involved is greater than in the case of one who is a neighbour of the mosque, in addition to the patience involved in doing this act of worship. Every prayer in which there is difficulty due to the distance walked brings a greater reward and is better than a prayer in which there is no difficulty. This is encouraging and urging the Muslim to pray in congregation, even if the mosque is far away. In Sahih Muslim it is narrated that when Banu Salamah wanted to move closer to the mosque of the Messenger of Allah (blessings and peace of Allah be upon him), he said to them: “O Banu Salamah, remain in your land and the reward for your steps will be recorded, remain in your land and the reward for your steps will be recorded.” What is meant is: stay where you are, and in return for the steps that you take to the mosque, more reward will be written for you because of having to walk further to reach the mosque. Similarly, the one who waits for the prayer so that he may pray with the imam in congregation will have a greater reward than the one who prays on his own as soon as the time for the prayer begins, then goes to sleep. Just as distance has an impact of increasing reward, waiting for a longer time also increases reward, because in both cases extra effort is required..
