عَنِ ابْنِ عَبَّاسٍ قَالَ: لَمَّا دَخَلَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ الْبَيْتَ دَعَا فِي نَوَاحِيهِ كُلِّهَا وَلَمْ يُصَلِّ حَتَّى خَرَجَ مِنْهُ فَلَمَّا خَرَجَ رَكَعَ رَكْعَتَيْنِ فِي قُبُلِ الْكَعْبَةِ وَقَالَ: «هَذِه الْقبْلَة» . رَوَاهُ البُخَارِيّ وَرَوَاهُ مُسْلِمٌ عَنْهُ عَنْ أُسَامَةَ بْنِ زَيْدٍ

Ibn ‘Umar reported God’s Messenger as saying, “Perform some of your prayer in your houses, and do not turn them into graves.”* * This is most probably a figurative expression indicating that a house in which prayer is not offered is like a grave, as God is not worshipped there.(Bukhari and Muslim.)
