You placed the Maqam Ibrahim between yourself and the door of the Sacred House and performed the prayer. You did not stand in front of the Maqam Ibrahim, nor to its right or left side.

A detailed narration regarding the Hajj of the Prophet Muhammad (peace be upon him) is reported from Sayyiduna Jabir bin Abdullah (may Allah be pleased with them both). He says: Then the Prophet performed ramal (brisk walking) in three circuits and walked normally in four circuits. Then he came to the Station of Ibrahim, then recited this verse «‏‏‏‏وَاتَّخِذُوا مِن مَّقَامِ إِبْرَاهِيمَ مُصَلًّى» ‏‏‏‏ [ سورة البقرة: 125 ] "And take the Station of Ibrahim as a place of prayer." The Prophet (peace be upon him) placed the Station of Ibrahim between himself and the door of the Sacred House (Ka'bah) while praying. When he finished the prayer, he came to the Sacred House and kissed the Black Stone. Then he narrated the rest of the hadith.
