The Ruling on Placing Mihrabs in Mosques

Question : Take from me, I leave it as an innovation.

Answer : Yes, yes, I do. No, this is said, and this is not present in the time of the Messenger (peace and blessings be upon him). The requirement in the time of the Messenger is not present regarding the mihrab. As for the mihrab, it is not from the Sunnah, but it is permissible. That is, we do not say we order people to have a mihrab, nor do we forbid it. We say it is among the permissible matters because of the sign it provides and the guidance to the direction of the qiblah. Did you not know that some people in this place entered and then prayed toward this place of ours? And did you not know that the carpets used to be spread in the mosques here with carpets that had mihrabs? So the carpet layer spread the mihrabs with their faces toward the back of the grave. So the people entered and began to pray, and the qiblah was behind them. We witnessed this in Riyadh.
These are mihrabs; we do not say they are from the Sunnah, but they are permissible, and we do not say they are disliked. And if you suppose that you entered the mosque and there is no mihrab and no marked lines on the rows, toward what do you turn? The minbar? Does every mosque have a minbar? The minbar is for Jumu'ah only, because of the Jumu'ah prayer.
