Yahya related to me from Malik from Zayd ibn Aslam from a man of the Bani'd-Dil called Busr ibn Mihjan from his father Mihjan that he was in a gathering with the Messenger of Allah ﷺ and the call to prayer was made. The Messenger of Allah ﷺ rose and prayed and then returned. Mihjan remained sitting and did not pray with him. The Messenger of Allah ﷺ said, "What prevented you from praying with the people? Aren't you a muslim?" He said, "Of course, Messenger of Allah, but I have already prayed with my family." The Messenger of Allah ﷺ said, "When you come, pray with the people, even if you have prayed already."  

أَنَّهُ كَانَ فِي مَجْلِسٍ مَعَ رَسُولِ اللَّهِ ﷺ فَأُذِّنَ بِالصَّلاَةِ فَقَامَ رَسُولُ اللَّهِ ﷺ فَصَلَّى ثُمَّ رَجَعَ وَمِحْجَنٌ فِي مَجْلِسِهِ لَمْ يُصَلِّ مَعَهُ فَقَالَ لَهُ رَسُولُ اللَّهِ ﷺ مَا مَنَعَكَ أَنْ تُصَلِّيَ مَعَ النَّاسِ أَلَسْتَ بِرَجُلٍ مُسْلِمٍ فَقَالَ بَلَى يَا رَسُولَ اللَّهِ وَلَكِنِّي قَدْ صَلَّيْتُ فِي أَهْلِي فَقَالَ لَهُ رَسُولُ اللَّهِ ﷺ إِذَا جِئْتَ فَصَلِّ مَعَ النَّاسِ وَإِنْ كُنْتَ قَدْ صَلَّيْتَ  

Yahya related to me from Malik from Nafi that a man asked Abdullah ibn Umar, "Sometimes I pray in my house, and then catch the prayer with the imam. Should I pray with him?" Abdullah ibn Umar said to him, "Yes," and the man said, "Which of them do I make my prayer?" Abdullah ibn Umar said, "Is that up to you? It is up to Allah. He will decide on whichever of them He wishes."  

فَقَالَ إِنِّي أُصَلِّي فِي بَيْتِي ثُمَّ أُدْرِكُ الصَّلاَةَ مَعَ الإِمَامِ أَفَأُصَلِّي مَعَهُ فَقَالَ لَهُ عَبْدُ اللَّهِ بْنُ عُمَرَ نَعَمْ فَقَالَ الرَّجُلُ أَيَّتَهُمَا أَجْعَلُ صَلاَتِي فَقَالَ لَهُ ابْنُ عُمَرَ أَوَذَلِكَ إِلَيْكَ إِنَّمَا ذَلِكَ إِلَى اللَّهِ يَجْعَلُ أَيَّتَهُمَا شَاءَ  

Yahya related to me from Malik from Yahya ibn Said that a man asked Said ibn al-Musayyab, "I pray in my house, and then I come to the mosque and find the imam praying. Should I pray with him?" Said said, "Yes," and the man said, "Which of them is my prayer?" Said said, "Are you the one to decide that? That is up to Allah."  

فَقَالَ إِنِّي أُصَلِّي فِي بَيْتِي ثُمَّ آتِي الْمَسْجِدَ فَأَجِدُ الإِمَامَ يُصَلِّي أَفَأُصَلِّي مَعَهُ فَقَالَ سَعِيدٌ نَعَمْ فَقَالَ الرَّجُلُ فَأَيُّهُمَا صَلاَتِي فَقَالَ سَعِيدٌ أَوَأَنْتَ تَجْعَلُهُمَا إِنَّمَا ذَلِكَ إِلَى اللَّهِ  

Yahya related to me from Malik from Afif as-Sahmi that a man from the tribe of Bani Asad asked Abu Ayyub al-Ansari. "Sometimes I pray in my house, and then come to the mosque and find the imam praying. Should I pray with him?" Abu Ayyub said, "Yes, pray with him, for some one who does so has the reward of the group, or the equivalent of the reward of the group."  

فَقَالَ إِنِّي أُصَلِّي فِي بَيْتِي ثُمَّ آتِي الْمَسْجِدَ فَأَجِدُ الإِمَامَ يُصَلِّي أَفَأُصَلِّي مَعَهُ فَقَالَ أَبُو أَيُّوبَ نَعَمْ فَصَلِّ مَعَهُ فَإِنَّ مَنْ صَنَعَ ذَلِكَ فَإِنَّ لَهُ سَهْمَ جَمْعٍ أَوْ مِثْلَ سَهْمِ جَمْعٍ  

Yahya related to me from Malik from Nafi that Abdullah ibn Umar used to say, "Someone who prays maghrib or subh and then catches them with the imam should not repeat them." Malik said, "I do not see any harm in someone who has already prayed in his house praying with the imam, except for maghrib, because if he repeats it, he makes it even."  

أَنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ كَانَ يَقُولُ مَنْ صَلَّى الْمَغْرِبَ أَوِ الصُّبْحَ ثُمَّ أَدْرَكَهُمَا مَعَ الإِمَامِ فَلاَ يَعُدْ لَهُمَا قَالَ مَالِكٌ وَلاَ أَرَى بَأْسًا أَنْ يُصَلِّيَ مَعَ الإِمَامِ مَنْ كَانَ قَدْ صَلَّى فِي بَيْتِهِ إِلاَّ صَلاَةَ الْمَغْرِبِ فَإِنَّهُ إِذَا أَعَادَهَا كَانَتْ شَفْعًا
