Riyad as-Saliheen 228
Abu Hurairah (May Allah bepleased with him) reported:
Messenger of Allah ﷺ said, "When one of you leads the Salat, he should not prolong it because the congregation includes those who are feeble, ill or old". One version adds: "those who have to attend to work") While offering prayers alone, you may pray as long as you like".
[Al-Bukhari and Muslim].
وعن أبي هريرة رضي الله عنه ، أن رسول الله ﷺ قال: "إذا صلى أحدكم للناس، فليخفف، فإن فيهم الضعيف والسقيم والكبير. وإذا صلى لنفسه فليطول ما شاء" ((متفق عليه)) . (10)
