فِيهِ ءَايَٰتٌۢ بَيِّنَٰتٌۭ مَّقَامُ إِبْرَٰهِيمَ ۖ وَمَن دَخَلَهُۥ كَانَ ءَامِنًۭا ۗ وَلِلَّهِ عَلَى ٱلنَّاسِ حِجُّ ٱلْبَيْتِ مَنِ ٱسْتَطَاعَ إِلَيْهِ سَبِيلًۭا ۚ وَمَن كَفَرَ فَإِنَّ ٱللَّهَ غَنِىٌّ عَنِ ٱلْعَٰلَمِينَ
Wherein are plain memorials (of Allah's guidance); the place where Abraham stood up to pray; and whosoever entereth it is safe. And pilgrimage to the House is a duty unto Allah for mankind, for him who can find a way thither. As for him who disbelieveth, (let him know that) lo! Allah is Independent of (all) creatures.
Surah Aal-i-Imraan(3:97)

Chapter: The sickness of the Prophet (saws) and his death
Narrated `Urwa bin Az-Zubair:
`Aisha said, "The Prophet (ﷺ) said during his fatal illness, "Allah cursed the Jews for they took the graves of their prophets as places for worship." `Aisha added, "Had it not been for that (statement of the Prophet ) his grave would have been made conspicuous. But he was afraid that it might be taken as a place for worship."
