Abu Huraira reported:The Apostle of Allah (ﷺ) said: When any one of you leads the people in prayer, he should be brief for among them are the young and the aged, the weak and the sick. But when one of you prays by himself, he may (prolong) as he likes

Hammam b. Munabbih reported:This is what Abu Huraira transmitted to us from Muhammad the Messenger of Allah (ﷺ), and he narrated (some) ahadith out of (these narrations and one of them is this): The Messenger of Allah (ﷺ) said: When any one of you stands to lead people In prayer, he should shorten it, for amongst them are the aged, and amongst them are the weak, but when he prays by himself, he may prolong his prayer as he likes

Abu Huraira reported:The Messenger of Allah (ﷺ) said: When any one of you leads people in prayer, he must shorten it for among them are the weak, the infirm and those who have business to attend

Abu Bakr b. 'Abd al-Rahman reported that he had heard Abu Huraira say that the Messenger of Allah (ﷺ) said like it, but he substituted" the aged" for 'the infirm
