On the twenty-third of Dhu’l-Qa’dah, AH 200, Imam Alī ibn Mūsā ar-Riḍā (عليه السلام) departed life, according to some narrations. Hence, it is familiar to visit his tomb on this day whether from nearby or from far off. In this respect, Sayyid Ibn Tawus, in Iqbal al-A’mal, says that he has seen in the book of some non-Arab scholars that it is recommended to visit the holy tomb of Imam al-Rida (عليه السلام) on the twenty-third of Dhu’l-Qa’dah from nearby or from far off by one of the familiar forms of Ziyarah or any other form.
