﴿ ۞ جَعَلَ ٱللَّهُ ٱلْكَعْبَةَ ٱلْبَيْتَ ٱلْحَرَامَ قِيَٰمًۭا لِّلنَّاسِ وَٱلشَّهْرَ ٱلْحَرَامَ وَٱلْهَدْىَ وَٱلْقَلَٰٓئِدَ ۚ ذَٰلِكَ لِتَعْلَمُوٓا۟ أَنَّ ٱللَّهَ يَعْلَمُ مَا فِى ٱلسَّمَٰوَٰتِ وَمَا فِى ٱلْأَرْضِ وَأَنَّ ٱللَّهَ بِكُلِّ شَىْءٍ عَلِيمٌ ﴾

“God has laid down that the Ka'bah, the Inviolable Temple, shall be a symbol for all mankind; and [so, too] the sacred month [of pilgrimage] and the garlanded offerings [are symbols] meant to make you aware that God is aware of all that is in the heavens and all that is on earth, and that God has full knowledge of everything.”
