يَحْذَرُ ٱلْمُنَٰفِقُونَ أَن تُنَزَّلَ عَلَيْهِمْ سُورَةٌۭ تُنَبِّئُهُم بِمَا فِى قُلُوبِهِمْ ۚ قُلِ ٱسْتَهْزِءُوٓا۟ إِنَّ ٱللَّهَ مُخْرِجٌۭ مَّا تَحْذَرُونَ
The hypocrites fear lest a surah should be revealed concerning them, proclaiming what is in their hearts. Say: Scoff (your fill)! Lo! Allah is disclosing what ye fear.
Surah At-Tawba(9:64)

Hajj (Pilgrimage)
Chapter: Offering As-Salat (the prayers) inside the Ka'bah
Narrated Nafi`:
Whenever Ibn `Umar entered the Ka`ba he used to walk straight keeping the door at his back on entering, and used to proceed on till about three cubits from the wall in front of him, and then he would offer the prayer there aiming at the place where Allah's Messenger (ﷺ) prayed, as Bilal had told him. There is no harm for any person to offer the prayer at any place inside the Ka`ba.
