Hadith 1440
tawafrights
وَاللهَ اللهَ فِي بَيْتِ رَبِّكُمْ، لَا تُخْلُوهُ مَا بَقِيتُمْ، فَإِنَّهُ إِنْ تُرِكَ لَمْ تُنَاظَرُوا.
(Fear) Allāh (and) keep Allāh in view in the matter of your Lord’s House (Ka‘bah). Do not forsake it so long as you live, because if it is abandoned you will not be spared.
