Question: Does calling the Prophet ﷺ Allah’s servant lessen his exalted rank?
Answer: No. Servanthood is part of the honor of the prophets, while messengership establishes his status as a chosen prophet who must be followed. True reverence preserves the distinction between Creator and creature.
وَإِنَّ مُحَمَّدًا صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ عَبْدُهُ الْمُصْطَفَى وَنَبِيُّهُ الْمُجْتَبَى وَرَسُولُهُ الْمُرْتَضَى
Muhammad ﷺ is His chosen servant, selected prophet and approved messenger.
Follow-up: Does love of the Messenger require attributing any divine quality to him?
Clarification: Certainly not. Love is expressed through obedience, respect and belief in his message, not by exceeding the bounds of monotheism.
