The Prophet (peace and blessings of Allah be upon him) used to love to prolong the prayer, but at the same time he would take the people's needs into consideration. He would sometimes shorten the prayer for the sake of certain individuals, as in this Hadith in which the Prophet (peace and blessings of Allah be upon him) said: “I stand to lead the prayer intending to prolong it.” That is, he intended to complete it and perfect it in the usual manner—not the kind of prolonging which the Prophet (peace and blessings of Allah be upon him) forbade the Imams from doing. “Then I hear the crying of an infant, so I shorten it,” meaning: he would hear the crying of a child who was present with his mother, who was praying in the congregation. So he would lighten the prayer and not prolong it in terms of recitation or other actions, “out of dislike for causing hardship to his mother,” meaning: out of compassion for the child and his mother, due to her being distracted by her child’s crying during the prayer.This Hadith highlights the importance of taking the condition of the congregation into account during the prayer, and of avoiding causing them hardship by unnecessary lengthening..
