The Prohibition of Using the Prophet's Kunya

This hadith from Al-Adab Al-Mufrad 836 establishes a clear distinction between using the Prophet's personal name (Muhammad) and his honorific kunya (Abu'l-Qasim). While the Prophet ﷺ encouraged Muslims to name their children after him, he explicitly forbade them from adopting his kunya, which means "Father of Qasim," referring to his deceased son.

Scholarly Commentary on the Wisdom Behind This Prohibition

Classical scholars explain that this prohibition serves multiple purposes. Firstly, it maintains the unique distinction and honor of the Prophet ﷺ as the final messenger. Secondly, it prevents potential confusion in identification when calling someone by their kunya. Thirdly, it reflects proper adab (etiquette) toward the Prophet's special status.

Imam al-Nawawi comments that this prohibition was particularly relevant during the Prophet's lifetime, though some scholars maintain its applicability after his passing as a mark of respect. The permission to use the name "Muhammad" demonstrates the honor of bearing the Prophet's name while maintaining proper boundaries.

Practical Application in Islamic Naming Conventions

This teaching has shaped Islamic naming practices for centuries. Muslims commonly name their children Muhammad, Ahmad, or other names of the Prophet ﷺ while avoiding the specific kunya Abu'l-Qasim. The wisdom behind this practice preserves the unique connection to the Prophet while maintaining proper reverence and distinction.

Scholars note that this prohibition applies specifically to the combination "Abu'l-Qasim" and does not extend to other honorable names or kunyas. The ruling exemplifies how Islamic teachings balance imitation of the Prophet with maintaining his special status as the final messenger to humanity.
