Muwatta Imam Malik Book of Prayer, Hadith 4

Yahya related to me from Malik from al-Ala ibn Abd ar-Rahman ibn Yaqub from his father and Ishaq ibn Abdullah that they informed him that they heard Abu Hurayra say, "The Messenger of Allah ﷺ said, 'When the iqama is called for prayer, do not come to it running, but come with calmness. Pray what you catch and complete what you miss. You are in prayer as long as your aim is the prayer.' "

وَحَدَّثَنِي عَنْ مَالِكٍ، عَنِ الْعَلاَءِ بْنِ عَبْدِ الرَّحْمَنِ بْنِ يَعْقُوبَ، عَنْ أَبِيهِ، وَإِسْحَاقَ بْنِ عَبْدِ اللَّهِ، أَنَّهُمَا أَخْبَرَاهُ أَنَّهُمَا، سَمِعَا أَبَا هُرَيْرَةَ، يَقُولُ قَالَ رَسُولُ اللَّهِ ﷺ " إِذَا ثُوِّبَ بِالصَّلاَةِ فَلاَ تَأْتُوهَا وَأَنْتُمْ تَسْعَوْنَ وَأْتُوهَا وَعَلَيْكُمُ السَّكِينَةُ فَمَا أَدْرَكْتُمْ فَصَلُّوا وَمَا فَاتَكُمْ فَأَتِمُّوا فَإِنَّ أَحَدَكُمْ فِي صَلاَةٍ مَا كَانَ يَعْمِدُ إِلَى الصَّلاَةِ " .
