Sayyiduna Abu Mas’ud Ansari (may Allah be pleased with him) narrated that a man came to the Messenger of Allah (peace and blessings be upon him) and said,“O Messenger of Allah, by Allah, I do not attend the morning congregation because of so-and-so (Mu’adh bin Jabal or Ubayy bin Ka’b), as he makes the prayer too long for us.”Abu Mas’ud said,“I have never seen the Messenger of Allah (peace and blessings be upon him) more angry in giving advice and admonition than he was that day. Then he said, ‘O people, some of you make others dislike (the prayer). So whoever among you leads the people in prayer should make it short, for among them are the elderly, the young, and those with needs.’”
