When a person is praying on his own, he may lengthen the prayer as he wishes, for that depends on his own desire and energy; nevertheless, he should limit it to a length that does not distract him from other obligatory duties.

The ḥadith teaches that the weak and the incapacitated must be considered in every matter shared with the strong—whether religious or social—because such consideration is obligatory and must be put into practice.

In “Tahdhīb al-ʿUmda” it is stated: “It is recommended for the imam to keep the prayer brief when he is being followed, and this brevity is appropriate so long as no congregant prefers a longer prayer. It is disliked to perform the prayer so quickly that a follower is unable to carry out the recommended acts.”
