عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ رَضِيَ اللَّهُ عَنْهُ قَالَ: سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ يَقُولُ: ((إِذَا قَضَى أَحَدُكُمْ صَلَاتَهُ فِي الْمَسْجِدِ ثُمَّ رَجَعَ إِلَى بَيْتِهِ حِينَئِذٍ فَلْيُصَلِّ فِي بَيْتِهِ رَكْعَتَيْنِ، وَلْيَجْعَلْ فِي بَيْتِهِ نَصِيبًا مِنْ صَلَاتِهِ، فَإِنَّ اللَّهَ جَاعِلٌ فِي بَيْتِهِ مِنْ صَلَاتِهِ خَيْرًا))
It is narrated from Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: When any one of you performs prayer in the mosque, then returns to his home, he should perform two rak'ahs in his house. A servant should continue to offer voluntary prayers in his house, because Allah Almighty sends goodness and blessings upon his house due to his prayer.
