Prayer in congregation is one of the practices and rituals of Islam. The Prophet (blessings and peace of Allah be upon him) enjoined it and warned against neglecting it and being heedless concerning it. In this hadith, there is a stern warning and threat from the Prophet (blessings and peace of Allah be upon him) to the one who stays away from prayer in congregation with no excuse. The Prophet (blessings and peace of Allah be upon him) swore an oath, saying: “By the One in Whose hand is my soul.” This is an oath by which the Messenger of Allah (blessings and peace of Allah be upon him) often swore. What it means is: By Allah, in Whose hand is my soul; this is an affirmation of the divine attribute of the hand, in a manner that is befitting to Allah’s majesty. The Prophet (blessings and peace of Allah be upon him) swore this oath, saying: “I thought of issuing orders that firewood be collected” – that is, I was about to issue orders that firewood – which is dry material from crops and trees – be collected, then issuing orders that the call to prayer be given, and instructing a man to lead the people in prayer; then I would not join the prayer in congregation, doing something different to my instruction to pray. I would go to some people who have stopped praying in congregation and have been praying in their houses, and burn their houses down with them inside. Then the Prophet (blessings and peace of Allah be upon him) swore the same oath again, for emphasis, saying: “By the One in Whose hand is my soul, if one of them knew that he would find a bone with meat on it, or the meat from a sheep’s foot, he would attend ‘Isha’.” The word translated here as a bone refers to a bone on which there is a little meat left. What is meant is that the Prophet (blessings and peace of Allah be upon him) was swearing that if those people who stayed away from prayer in congregation with no excuse knew that, if they attended the prayer, they would find some worldly benefit, such as food for example, even if that worldly benefit was of very little significance, they would attend and join the worshippers, because all they cared about was worldly benefit, and they did not care about what would benefit them in the hereafter. This hadith emphasizes the importance of praying in congregation, and warns against missing it with no excuse. It indicates that it is permissible for one who is of lower standing to lead the prayer in the presence of one who is of higher standing, if that serves a purpose..
