Qur'an 5:97

۞ جَعَلَ ٱللَّهُ ٱلْكَعْبَةَ ٱلْبَيْتَ ٱلْحَرَامَ قِيَـٰمًا لِّلنَّاسِ وَٱلشَّهْرَ ٱلْحَرَامَ وَٱلْهَدْىَ وَٱلْقَلَـٰٓئِدَ ۚ ذَٰلِكَ لِتَعْلَمُوٓا۟ أَنَّ ٱللَّهَ يَعْلَمُ مَا فِى ٱلسَّمَـٰوَٰتِ وَمَا فِى ٱلْأَرْضِ وَأَنَّ ٱللَّهَ بِكُلِّ شَىْءٍ عَلِيمٌ

Allah hath appointed the Ka'bah, the Sacred House, a standard for mankind, and the Sacred Month and the offerings and the garlands. That is so that ye may know that Allah knoweth whatsoever is in the heavens and whatsoever is in the earth, and that Allah is Knower of all things.
