that 'Umar bin Al-Khattab said: "O Messenger of Allah ﷺ! I wish that we could perform Salat behind the Maqam: So the following was revealed: And take you the Maqam of Ibrahim as a place of Salat. (2:125)."
يَا رَسُولَ اللَّهِ لَوْ صَلَّيْنَا خَلْفَ الْمَقَامِ فَنَزَلَتْ (وَاتَّخِذُوا مِنْ مَقَامِ إِبْرَاهِيمَ مُصَلًّى )
