وَحَدَّثَنَا ابْنُ الْمُثَنَّى، حَدَّثَنَا عَبْدُ الْوَهَّابِ، أَخْبَرَنَا أَيُّوبُ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " صَلُّوا فِي بُيُوتِكُمْ وَلاَ تَتَّخِذُوهَا قُبُورًا " .
Ibn 'Umar reported Allah's Apostle (ﷺ) as saying: Pray in your houses, and do not make them graves.
