The Sahabah (may Allah be pleased with them) would hasten to comply with the instructions of the Prophet (blessings and peace of Allah be upon him), and they would strive hard to do things as the Messenger of Allah (blessings and peace of Allah be upon him) enjoined them, and to teach this to those who came after them, especially with regard to prayer, which is the foundation of faith. In this hadith, the Messenger of Allah (blessings and peace of Allah be upon him) instructed his companions (may Allah be pleased with them) to straighten their rows, which means that the people standing in the row should make it a straight and even line, with no one standing out. It also means filling the gaps that may appear in the row. The Messenger of Allah (blessings and peace of Allah be upon him) explained the reason for this instruction by telling them about one of his miracles, as he said: “for I can see you behind my back.” What is meant is: I only instruct you to do that because I am aware that you are falling short in this regard, because I can see you behind me. It may be that he said this to encourage the weak to straighten their rows, because they did not straighten their rows properly as they thought that he could not see them; that is because many of the weak pay more attention when they are watched than when they are not watched. It may be that some of the hypocrites did not pay attention to straightening the rows, so this was said to them in order to make them pay attention and not cause the rows to be ragged. What is meant by seeing in the Prophet’s words “for I can see you behind my back” is to be understood as it appears to be, and that he was able to see them in the true sense of the word, which was something extraordinary that was unique to the Prophet (blessings and peace of Allah be upon him); this was one of his miracles. Then Anas ibn Malik (may Allah be pleased with him) – the narrator of the hadith – explained how they complied with the instruction of the Messenger of Allah (blessings and peace of Allah be upon him) to straighten their rows: each of them would make his shoulder touch the shoulder of the person next to him – the word translated here as shoulder refers to where the top of the arm meets the torso. And each of them would make his foot touch the foot of the person next to him, so as to ensure that the row would be straight, in fulfilment of the command of the Prophet (blessings and peace of Allah be upon him). In this hadith, we see the command to straighten the rows and make them look good whilst praying, and the command to the imam to make sure that the people do that; the people themselves should also make sure that they are doing that. It indicates that it is permissible to speak between the iqamah and the prayer. .
