He reported that he had heard God’s Messenger say, “Do not turn your houses into graves,* and do not make my grave a place to gather as for visitation, but invoke blessings on me, for your blessing will reach me wherever you are.” *This is most probably a figurative expressive indicating that a house in which prayer is not offered is like a grave, as God is not worshipped there. Nasa’i transmitted it.
وَعَنْهُ قَالَ: سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ: «لَا تَجْعَلُوا بُيُوتَكُمْ قُبُورًا وَلَا تَجْعَلُوا قَبْرِي عِيدًا وَصَلُّوا عَلَيَّ فَإِنَّ صَلَاتكُمْ تبلغني حَيْثُ كُنْتُم» . رَوَاهُ النَّسَائِيّ
