(Imām Bukhārī narrates): Adam narrated to us, he said: Ibn Abi Dhi'b narrated to us, he said: Az-Zuhri narrated to us from Sa'id and Abu Salamah from Hazrat Abu Hurairah, may Allāh be pleased with him, from the Prophet ﷺ. H And Abul Yaman narrated to us, he said: Shu'aib informed us from Az-Zuhri, he said: Abu Salamah bin Abdur Rahman informed me that Hazrat Abu Hurairah, may Allāh be pleased with him, narrated that I heard the Messenger of Allāh ﷺ saying that
when the Iqamah for the prayer is said, do not come running, but come walking, and hold firmly to calmness. So whatever of the prayer you catch, offer it, and whatever of it you have missed, complete it.
حَدَّثَنَا آدَمُ، قَالَ حَدَّثَنَا ابْنُ أَبِي ذِئْبٍ، قَالَ الزُّهْرِيُّ، عَنْ سَعِيدٍ، وَأَبِي سَلَمَةَ، عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ، عَنِ النَّبِيِّ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ، ح وَحَدَّثَنَا أَبُو اليَمَانِ، قَالَ أَخْبَرَنَا شُعَيْبٌ، عَنِ الزُّهْرِيِّ، قَالَ أَخْبَرَنِي أَبُو سَلَمَةَ بْنُ عَبْدِ الرَّحْمَنِ أَنَّ أَبَا هُرَيْرَةَ
قَالَ سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ يَقُولُ إِذَا أُقِيمَتِ الصَّلاَةُ ، فَلاَ تَأْتُوهَا تَسْعَوْنَ، وَأْتُوهَا تَمْشُونَ، عَلَيْكُمُ السَّكِينَةُ، فَمَا أَدْرَكْتُمْ فَصَلُّوا، وَمَا فَاتَكُمْ فَأَتِمُّوا
