Is the Messenger's speech in religion and worldly affairs all revelation?

Question:
May Allah reward you, Your Eminence, father. The questioner says: Some have mentioned that the speech of the Prophet (peace and blessings be upon him) is not all revelation, and they cited the saying of the Prophet (peace and blessings be upon him), "You know best the affairs of your worldly lives." The question is: Is this correct? And how is it, when the Prophet (peace and blessings be upon him) said to 'Ali ibn Abi Talib (may Allah be pleased with him), "Write, and by Myself in Whose Hand is my soul, I do not say anything except the truth."

Answer:
The speech of the Prophet (peace and blessings be upon him) in matters of religion is only by revelation. As for his speech in matters of custom and worldly affairs, it is not necessary that it be by revelation. There is no one who says that his speech in matters of custom is revelation. Rather, his speech (peace and blessings be upon him) in matters of religion is certainly revelation from Allah (Mighty and Majestic). Whoever denies this is denying the Messenger (peace and blessings be upon him). "You know best the affairs of your worldly lives" is from the affairs of the world, not from the affairs of religion. Pollinating the date palms is not from the affairs of religion, but rather from the affairs of the world. May Allah will it, peace be upon you. He said it to 'Ali ibn Abi Talib (may Allah be pleased with him). Rather, he said it to 'Abdullah ibn 'Amr ibn al-'As. He said to him, "Write." Yes.
