Al-Ṭabarī said, “The boundary of the area where the pebbles gather is three cubits from the base of the jamrah.”

Ibn Ḥajar al-Haytamī added, “Direct observation confirms this, for that gathering area is, in most cases, no smaller than that.”

The compiler of this book notes: “Until recent times, the targets of the three jamarāt were not surrounded by a wall. The first to mention the construction of these walls around the jamarāt is Shaykh ʿAlī b. Sālim al-Ḥaḍramī in his pilgrimage manual Dalīl al-Ṭarīq li-Ḥujjāj Bayt Allāh al-ʿAtīq; on page (87) he writes: ‘The marmaʾ (target area), the spot where the marker is set up, has been fixed at three cubits on every side and that space has been enclosed by a low wall; the stoning is to be done inside it.’ This was discussed earlier.”

Decision of the Council of Senior Scholars regarding the jamarāt basin:

Its summary is as follows:

It was unanimously resolved that it is impermissible to build a basin larger than the one currently in place, and that it must remain as it is. It is also understood that once a pebble reaches the basin the rite is fulfilled, even if it does not stay there but rolls out.
