Is it forbidden to manufacture and export uniquely shaped candles that are used in celebrating the Prophet's Birthday (Mawlid al-Nabawi)? If permissible, is there any objection to exporting them a few days before the celebration?

Celebrating the Prophet's Birthday (Mawlid) is an innovated Bid'ah, and it is not permissible to assist in it in any way, based on the words of Allah Almighty: "And cooperate in righteousness and piety, but do not cooperate in sin and aggression." Therefore, if the candles are used only for celebrating the Prophet's Birthday, or if it is highly probable that the buyers will use them for that purpose, then it is not permissible to sell them to them.
