الشرح المختصر :

"A‘lām al-Haram" (Haram signposts) are the signposts constructed at the boundaries of the Sacred Mosque in Makkah as well as in Madinah. The first to erect them was Prophet Ibrāhim (Abraham), peace be upon him, after being told by Archangel Jibreel (Gabriel) where to place them. The Messenger of Allah, may Allah’s peace and blessings be upon him, then ordered his Companions to renovate these signs that Ibrāhim had built. ‘Umar, ‘Uthmān, and then Mu‘āwiyah, may Allah be pleased with them, did the same, as well as other Caliphs who came after them. These signs are still clear until this day - praise be to Allah - written in Arabic as well as in other languages, indicating the start and end of sacred precincts in Makkah and Madinah.
