It was narrated that Anas bin Malik told that ‘Umar said: “I said: ‘O Messenger of Allah, why do you not take the Maqam of Ibrahim as a place of prayer?’ Then the following was revealed: ‘And take you (people) the Maqam of Ibrahim as a place of prayer.’” [2:125]

حَدَّثَنَا مُحَمَّدُ بْنُ الصَّبَّاحِ، حَدَّثَنَا هُشَيْمٌ، عَنْ حُمَيْدٍ الطَّوِيلِ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ قَالَ عُمَرُ قُلْتُ يَا رَسُولَ اللَّهِ لَوِ اتَّخَذْتَ مِنْ مَقَامِ إِبْرَاهِيمَ مُصَلًّى فَنَزَلَتْ ‏{وَاتَّخِذُوا مِنْ مَقَامِ إِبْرَاهِيمَ مُصَلًّى}‏ ‏.‏
