Do the Messengers receive money in exchange for conveying the message, based on the noble verse: "O you who have believed, when you [wish to] privately consult the Messenger, present before your private consultation [some] charity. That is better for you and purer. But if you find not [the means to do so] – then indeed, Allah is Forgiving and Merciful"?

The verse of An-Najwa (private consultation) has no connection to prophets receiving wages. It was revealed to regulate Muslims' private consultations with the Prophet, peace and blessings be upon him, and their frequent questioning of him. This was for several reasons, including: magnifying the Messenger, prohibiting excessive questioning, distinguishing the sincere from the hypocrite, and benefiting the poor Muslims through charity.

The Messengers, peace be upon them, did not receive wages for conveying their messages, because they conveyed them seeking Allah's reward. The proof for this is the saying of Noah, Hud, Saleh, Lut, and Shu'ayb, peace be upon them: "And I ask no reward for it from you. My reward is only from the Lord of the worlds" (Quran 26:109, 127, 145, 164, 180), and the saying of Prophet Muhammad, peace and blessings be upon him: "Say, 'I ask of you no reward for it'" (Quran 6:90, 38:86).
