According to search-discovered classical Islamic scholarship, Quran 33:51 details one of the well-established 'Khasā'is al-Nabī'—the unique characteristics and rulings granted exclusively to Prophet Muhammad (ﷺ). The verse specifically gave him divine permission and choice in the division of his time among his wives, exempting him from the strict obligation of equality that is otherwise required. Tafsir authorities like Al-Qurtubi clarify this was a divine concession to ease the immense burdens of his prophetic mission and public duties. Ibn Kathir's analysis further notes that despite this permission, the Prophet (ﷺ) often chose to maintain equality out of his noble character, demonstrating perfect justice voluntarily. This synthesis, grounded in historical context from scholars like Al-Tabari, establishes that this exemption was not a command but a divine honor, reflecting the Prophet's unique station and is unequivocally not applicable to any other Muslim.
