Abu Hurairah (May Allah be pleased with him) reported:
I heard the Messenger of Allah (ﷺ) saying, "When the Iqamah are pronounced, do not come to it running, you should walk calmly with tranquillity to join the congregation. Then join in what you catch for and complete what you miss."[Al-Bukhari and Muslim].In Muslim it is added: Messenger of Allah (ﷺ) said, "For when one of you is walking for Salat, he is, in fact, engaged in Salat."
