One of the fascinating features of Qur’anic rhetoric is that the choice of a single grammatical form can sometimes convey a profound theological message. A striking example occurs in the story of Prophet Mūsā (as) and his brother Hārūn (as), where the Qur’an employs an unexpected expression that has attracted the attention of scholars for centuries.
Allah commands them:
فَأْتِيَا فِرْعَوْنَ فَقُولَا إِنَّا رَسُولُ رَبِّ الْعَالَمِينَ
"Go to Pharaoh and say, 'Indeed, we are the Messenger of the Lord of the Worlds.'" (Qur'an 26:16)
At first glance, one word appears surprising.
An Unexpected Grammatical Choice
Mūsā and Hārūn are two individuals speaking together, so one might naturally expect them to say:
إِنَّا رَسُولَا رَبِّ الْعَالَمِينَ
“Indeed, we are the two messengers of the Lord of the Worlds.”
Instead, the Qur’an uses the singular noun:
رَسُول (Messenger)
This immediately raises an interesting question.
Why does the Qur’an describe two prophets with a singular noun?
One Mission, One Message
Classical scholars have offered a number of grammatical explanations for this construction, but many scholars of Laṭāʾif al-Qur’an also drew attention to its rhetorical beauty.
Although Mūsā and Hārūn were two individuals, they had not come with two different missions, two different revelations, or two competing messages. They had been sent by the same Lord, carrying the same revelation, inviting Pharaoh to the same truth. In that sense, they functioned as a single messengerial mission.
The singular noun beautifully reflects the unity of their purpose, even though the individuals themselves are two.
The Unity of the Prophetic Mission
This observation extends beyond Mūsā and Hārūn. Throughout the Qur’an, all of the prophets call mankind to the same fundamental truth: the worship of Allah alone and submission to Him. Their laws may differ according to time and circumstance, but the essence of their message remains one.
Seen from this perspective, the singular “Messenger” becomes a subtle reminder that the prophetic mission itself is one continuous and unified reality. Whether carried by one prophet or several, the source is one, the Caller is One, and the message is one.
A Reflection
The Qur’an frequently employs language in ways that invite the reader to reflect beyond the immediate wording. Here, an unexpected grammatical choice encourages us to think not only about the two individuals standing before Pharaoh, but also about the unity that binds every messenger of Allah throughout history.
It is observations such as these that form part of the study of Laṭāʾif al-Qur’an. By paying attention to the Qur’an’s precise choice of words and grammatical forms, we discover that even a single noun can open the door to profound theological reflection.
