in the obligatory (fard) prayer, because it has not been transmitted from the Prophet (peace and blessings of Allah be upon him) regarding the obligatory prayer, despite the multitude of those who described his recitation therein.

Section: It is recommended for the Imam to regulate the recitation, glorification (tasbih), and the tashahhud according to the extent that he perceives that those behind him, from those whose speech is labored, have achieved it, and to remain steady in his bowing and prostration for the duration that he perceives the elderly, the young, and the heavy [of movement] have achieved it. If he acts contrary to this and performs it in the [usual] extent, it is disliked but it suffices him. It is not recommended for him to prolong it excessively, as it would cause hardship for those behind him, based on the saying of the Prophet (peace and blessings of Allah be upon him): "Whoever leads the people in prayer, let him lighten it" (29). As for the individual praying alone, he may prolong all of that, provided it does not lead him to a state where he fears forgetfulness, in which case increasing it is disliked. It has been narrated from 'Ammar that he prayed a prayer in which he was brief. He was asked about that, and he said: "I am forestalling the whisperings of the devil (waswas)."

It is recommended for the Imam, if an exigency arises during the prayer for some of the followers that necessitates them leaving, to lighten it. It has come from the Prophet (peace and blessings of Allah be upon him) that he said: "I stand in prayer and I intend to prolong it, then I hear the crying of an infant and I expedite it, out of dislike for causing hardship to his mother." It was narrated by Abu Dawud (30).

181 - Issue: He said: (Then he performs the taslim to his right, saying: "Peace be upon you and the mercy of Allah." And likewise to his left.)

The sum of it is that when he finishes his prayer and intends to exit it, he performs the taslim to his right and to his left. This taslim is obligatory and nothing else can take its place. This is the opinion of Malik and al-Shafi'i.
