“A group from the people of ‘Iraq came to ‘Umar and when they came to him, he said to them: ‘Where are you from?’ They said: ‘From the inhabitants of ‘Iraq.’ He said: ‘Have you come with permission?’ They said: ‘Yes.’ Then they asked him about a man’s prayer in his house. ‘Umar said: ‘I asked the Messenger of Allah ﷺ and he said: “As for a man’s prayer in his house, it is light, so illuminate your houses.’”” Another chain with similar wording.  

خَرَجَ نَفَرٌ مِنْ أَهْلِ الْعِرَاقِ إِلَى عُمَرَ فَلَمَّا قَدِمُوا عَلَيْهِ قَالَ لَهُمْ مِمَّنْ أَنْتُمْ قَالُوا مِنْ أَهْلِ الْعِرَاقِ قَالَ فَبِإِذْنٍ جِئْتُمْ قَالُوا نَعَمْ قَالَ فَسَأَلُوهُ عَنْ صَلاَةِ الرَّجُلِ فِي بَيْتِهِ فَقَالَ عُمَرُ سَأَلْتُ رَسُولَ اللَّهِ ﷺ فَقَالَ أَمَّا صَلاَةُ الرَّجُلِ فِي بَيْتِهِ فَنُورٌ فَنَوِّرُوا بُيُوتَكُمْ حَدَّثَنَا مُحَمَّدُ بْنُ أَبِي الْحُسَيْنِ حَدَّثَنَا عَبْدُ اللَّهِ بْنُ جَعْفَرٍ قَالَ حَدَّثَنَا عُبَيْدُ اللَّهِ بْنُ عَمْرٍو عَنْ زَيْدِ بْنِ أَبِي أُنَيْسَةَ عَنْ أَبِي إِسْحَاقَ عَنْ عَاصِمِ بْنِ عَمْرٍو عَنْ عُمَيْرٍ مَوْلَى عُمَرَ بْنِ الْخَطَّابِ عَنْ عُمَرَ بْنِ الْخَطَّابِ عَنِ النَّبِيِّ ﷺ نَحْوَهُ  

“When anyone of you has finished his prayer, let him give his house a share of that, for Allah will put something good in his house because of that prayer.”  

عَنِ النَّبِيِّ ﷺ قَالَ إِذَا قَضَى أَحَدُكُمْ صَلاَتَهُ فَلْيَجْعَلْ لِبَيْتِهِ مِنْهَا نَصِيبًا فَإِنَّ اللَّهَ جَاعِلٌ فِي بَيْتِهِ مِنْ صَلاَتِهِ خَيْرًا  

“The Messenger of Allah ﷺ said: ‘Do not make your houses into graves.’”  

قَالَ رَسُولُ اللَّهِ ﷺ لاَ تَتَّخِذُوا بُيُوتَكُمْ قُبُورًا  

“I asked the Messenger of Allah ﷺ: ‘Which is better prayer in my house or prayer in the mosque?’ He said: ‘Do you not see how close my house is to the mosque?’ But praying in my house is dearer to me than praying in the mosque, apart from the prescribed prayers.’”  

سَأَلْتُ رَسُولَ اللَّهِ ﷺ أَيُّمَا أَفْضَلُ الصَّلاَةُ فِي بَيْتِي أَوِ الصَّلاَةُ فِي الْمَسْجِدِ قَالَ أَلاَ تَرَى إِلَى بَيْتِي مَا أَقْرَبَهُ مِنَ الْمَسْجِدِ فَلأَنْ أُصَلِّيَ فِي بَيْتِي أَحَبُّ إِلَىَّ مِنْ أَنْ أُصَلِّيَ فِي الْمَسْجِدِ إِلاَّ أَنْ تَكُونَ صَلاَةً مَكْتُوبَةً
