(442) بَابُ ذِكْرِ الدَّلِيلِ عَلَى أَنَّ الْمَسْبُوقَ بِرَكْعَةٍ أَوْ ثَلَاثٍ لَا تَجِبُ عَلَيْهِ سَجْدَتَا السَّهْوِ بِجُلُوسِهِ فِي الْأُولَى وَالثَّالِثَةِ اقْتِدَاءً بِإِمَامِهِ،The chapter on the evidence that someone who missed a unit or three behind the imam does not owe prostrations of forgetfulness for sitting in the first and third units following the imam
Hadith 1065
نَا عَلِيُّ بْنُ حُجْرٍ ، نَا إِسْمَاعِيلُ ، نَا الْعَلاءُ ، عَنْ أَبِيهِ ، عَنْ أَبِي هُرَيْرَةَ ، أَنّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ ، قَالَ : " إِذَا ثُوِّبَ لِلصَّلاةِ فَلا تَأْتُوهَا وَأَنْتُمْ تَسْعَوْنَ ، وَأْتُوهَا وَعَلَيْكُمُ السَّكِينَةُ ، فَمَا أَدْرَكْتُمْ فَصَلُّوا ، وَمَا فَاتَكُمْ فَأَتِمُّوا ؛ فَإِنَّ أَحَدَكُمْ إِذَا كَانَ يَعْمَدُ إِلَى الصَّلاةِ ، فَهُوَ فِي صَلاةٍ "
It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) said: "When the iqamah for prayer is called, do not come to prayer running, but come to prayer with calmness and tranquility. Whatever part of the prayer you catch, perform it, and whatever you miss, complete it. For when any one of you intends to pray, he is considered to be in the state of prayer."
