A principle of jurisprudence: the bare action of the Messenger of Allah indicates recommendation

Question : There is a principle that states that the action of the Prophet indicates recommendation, not obligation, and that obligation is indicated by the presence of a sign in the hadith, the right hand for the aforementioned principle. The question is: Is the statement of 'Umar in the hadith of Hauran a sign indicating the obligation of order in a single limb, meaning that the right must be preceded over the left?

Answer : The principle mentioned by the questioner is correct, and it is that the bare action of the Prophet (peace and blessings be upon him) indicates recommendation only, not obligation. And Allah the Exalted said in the Qur'an If the order had been obligatory, Allah would have mentioned the right before the left, just as He specified the limit of the full ritual bath by saying "to the elbows." The correct view is that the order between the right and the left in the chapter of ablution is by way of recommendation, not by way of obligation. So if a person starts with the left before the right, there is no blame on him.
