The Book of Good Manners
Excellence of Walking Solemnly (Towards the Mosque) to Perform As-Salat (The Prayer) and Other Religious Duties
وَعَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ قَالَ: سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّه عَلَيْهِ وَسَلَّمَ يَقُولُ: “إِذَا أُقِيمَتِ الصَّلاَةُ، فَلاَ تَأْتُوهَا وأنتم تسعون، وأتوها وَأَنْتُمْ تَمْشُونَ، وَعَلَيْكُمُ السَّكِينَةُ، فَمَا أَدْرَكْتُمْ فَصَلُّوا، وَمَا فَاتَكُمْ فَأَتِمُّوا” ((مُتَّفَقٌ عَلَيْهِ)) زَادَ مُسْلِمٌ فِي رواية له: فَإِنَّ أَحَدَكُمْ إِذَا كَانَ يَعْمِدُ إِلَى الصَّلاَةِ فَهُوَ فِي صَلاَةٍ .
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."
