It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that the Prophet (peace and blessings be upon him) said: "Saddles should be fastened on mounts (with the intention of worship and reward) only to travel to three mosques: al-Masjid al-Haram, this mosque of mine, and al-Masjid al-Aqsa."
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Hisham bin al-Ghaz except Ali bin Yunus, and Ali bin Siyabah is alone in narrating it."
It is like this in the printed edition of Dar al-Haramayn, whereas the correct form is 'Ya'la'.
