The Ruling on the Mihrab in the Mosque

Question:
Something is said after the Prophet (peace and blessings be upon him) entered the mosque, and we ask about these hadiths

Answer:
No, it is not an innovation. The establishment of mihrabs is well known among Muslims from ancient times. The jurists have mentioned that the qiblah is indicated by the mihrabs, which indicates that mihrabs existed from an early period among the Muslims and were well known to them. The mihrab is made to indicate the qiblah and the position of the imam. It is disliked for the imam to enter it and pray inside it.
Because the ma'mums cannot see him if he prays inside the niche. However, the niche is there for the purpose of indicating the qiblah. So, if you enter a mosque that does not have a mihrab and you do not know the qiblah, you will be confused and not know where to pray. You are in the mosque and do not know where to pray. But if there is a mihrab, you know the qiblah immediately. It is part of the practice of the Muslims and does not reach the level of bid'ah (religious innovation). Those who say it is an innovation are exaggerating in this matter. Yes.
