Hadith.2319 - Imam Jafar ibn Muhammad Al-Sadiq (as) said: "The height of the Kaaba was nine cubits, and it had no roof. The Quraysh then roofed it, raising its height to eighteen cubits. Later, Al-Hajjaj demolished it during his conflict with Ibn Al-Zubayr and rebuilt it, raising its height to twenty-seven cubits."
