Chapter on the Reasons Behind Hajj
Man Lā Yaḥḍuruh al-Faqīh|Volume 2|Book 3|Chapter 1
وَ قَدْ رُوِيَ: أَنَّهُ «إِنَّمَا سُمِّيَتْ كَعْبَةً لِأَنَّهَا مُرَبَّعَةٌ وَ صَارَتْ مُرَبَّعَةً لِأَنَّهَا بِحِذَاءِ اَلْبَيْتِ اَلْمَعْمُورِ وَ هُوَ مُرَبَّعٌ وَ صَارَ اَلْبَيْتُ اَلْمَعْمُورُ مُرَبَّعاً لِأَنَّهُ بِحِذَاءِ اَلْعَرْشِ وَ هُوَ مُرَبَّعٌ وَ صَارَ اَلْعَرْشُ مُرَبَّعاً لِأَنَّ اَلْكَلِمَاتِ اَلَّتِي بُنِيَ عَلَيْهَا اَلْإِسْلاَمُ أَرْبَعٌ وَ هِيَ: سُبْحَانَ اَللَّهِ وَ اَلْحَمْدُ لِلَّهِ وَ لاَ إِلَهَ إِلاَّ اَللَّهُ وَ اَللَّهُ أَكْبَرُ ».
It is narrated: "The Ka'bah was named 'Ka'bah' because it is cubical in shape. It became cubical because it is directly beneath the Bayt al-Ma‘mur, which is also cubical. The Bayt al-Ma‘mur became cubical because it is directly beneath the Throne (‘Arsh), which is cubical as well. The Throne is cubical because the foundational words upon which Islam is built are four: Subhan Allah سبحانه وتعالى (Glory be to Allah سبحانه وتعالى), Alhamdulillah (Praise be to Allah سبحانه وتعالى), La ilaha illa Allah سبحانه وتعالى (There is no god but Allah سبحانه وتعالى), and Allahu Akbar (Allah سبحانه وتعالى is the Greatest)."
