The ruling on lines drawn on mosque carpets

Question:
Honorable Shaykh Ahmad (may Allah have mercy on him). There is a principle that states: whatever does not require the action of the Messenger of Allah (peace and blessings be upon him), and was not established after him, is a bid'ah (religious innovation). Based on this, they ruled that the lines present in mosques are a bid'ah because the need for the worship of the Prophet (peace and blessings be upon him) was centered on it and did not leave it.

Answer:
This is an exaggeration and does not apply to the lines on the carpet or on the floor being a bid'ah. This is one of the ordinary matters, one of the matters of custom. However, one might say that this is an affectation, that this is an affectation. It should be left because it is an affectation that we were not commanded to do. As for ruling that it is a bid'ah, that is a hasty judgment. But this is an affectation and there is no need for it, and the worshippers face the qiblah without these things.
Yes, without these lines, they face the qiblah. The qiblah is known, its direction is known. A mihrab in the mosque is sufficient. A mihrab in the mosque is sufficient, because it is a sign of the qiblah. They face the direction of the mihrab, the direction of the imam. Yes, and there is no need for the lines. Yes.
