There are no narrations from the Infallibles (peace be upon them) about this mosque. In the book of Mafatih al-Jinan, it is mentioned that a man saw in his dreams that Imam Mahdi (peace be upon him) ordered him to build a mosque in this particular place and to offer four rak’at prayer. Since one cannot rely on dreams to prove religious rulings, one should not recite the prayers in the said mosque specifically because of any specific religious recommendation. However, one can worship and pray there for the sake of Almighty Allah as in any other mosque.
