Prayer is an act of worship which requires presence of mind and ease of movement. Hence the Prophet (blessings and peace of Allah be upon him) explained the rulings on prayer and the related rulings on leading prayer and making it brief and easy for the people. In this hadith, Abu Mas‘ud al-Ansari (may Allah be pleased with him) narrates that a man complained to the Messenger of Allah (blessings and peace of Allah be upon him) that he was not able to keep up with the prayer, because the imam made it so lengthy. There is a difference of scholarly opinion concerning what was meant by the man’s words, “I can hardly keep up with the prayers, because So-and-so makes them too lengthy for us.” It was said that the wording may indicate that he was a man who was sick or physically weak, so if the imam made the standing too long, then as soon as he reached the positions of bowing or prostrating, he would feel too weak to keep up with him, so he would hardly be able to bow or prostrate with him. Or it was said: rather it is explained by what al-Bukhari narrated, [that the man said]: I join the prayer late. In that case the meaning would be: I can hardly catch up with the prayer in congregation, and sometimes I come late, because he makes it so lengthy, so I do not catch up with the congregation, even though he makes it too long. The Prophet (blessings and peace of Allah be upon him) got very angry, and the reason why he showed such anger was that he wanted his Companions to pay attention to what he was going to tell them, so that the one who did that would not repeat it. Therefore he exhorted them when he was very angry, telling them that those who made the prayer too long were putting people off, and making people dislike praying. The reason why he addressed everyone, and did not mention by name the one who was making the prayer lengthy, was out of kindness and gentleness, as was his usual approach. He did not address any rebuke or discipline specifically to the one who deserved it, so that that one would not be embarrassed and feel ashamed in front of people. Then he instructed the one who led people in prayer to make the prayer shorter, because among the congregation were those who were sick, physically weak and had needs. He mentioned these three types, because they include all types of reasons why the prayer should be made brief, for the reasons which dictate making the prayer brief include either physical well-being or other matters. So in the first case, it is either because of something inherent, namely physical weakness, or something temporary, namely sickness. The Prophet (blessings and peace of Allah be upon him) wanted to show kindness and make things easy for his ummah. He did not prohibit making prayers lengthy because doing so is not permissible; rather the one who wants to offer supererogatory prayers by himself may make the prayer lengthy. This hadith is a rebuke to those who make the prayers lengthy if those praying behind him are not happy with that. It highlights the kindness of the Lawgiver and how he made things easy for his ummah. It also indicates that one may show anger when seeing something that is not appropriate with regard to matters of religion..
