وَ سَأَلَ مُحَمَّدُ بْنُ عِمْرَانَ اَلْعِجْلِيُّ أَبَا عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ: أَيَّ شَيْءٍ كَانَ مَوْضِعُ اَلْبَيْتِ حَيْثُ كَانَ اَلْمَاءُ فِي قَوْلِ اَللَّهِ تَعَالَى: «وَ كٰانَ عَرْشُهُ عَلَى اَلْمٰاءِ» قَالَ «كَانَتْ مَهَاةً بَيْضَاءَ يَعْنِي دُرَّةً.
Muhammad ibn Imran Al-'Ijli asked Abu Abdullah عليه السلام: "What was the location of the House (Kaaba) when the water existed, as mentioned in the words of Allah سبحانه وتعالى, the Exalted: 'And His Throne was upon the water'?" Imam عليه السلام replied: "It was a white expanse, meaning a pearl."
