<p class='libAr' dir='rtl'>فالوجه فيه أيضا ما قلناه من أن الذي يملأ الأرض قسطاً وعدلاًيكون من ولده دون ولد إسماعيل على ما ذهب إليه قوم فلذلك قرنه بالإيمان علما منه بأن قوما يعتقدون في ولد إسماعيل هذا فنفاه وقرنه بالإيمان لتزول الشبهة والشك والريبة.Explanation: As we mentioned before, one who would fill up the earth with justice and equity is from the descendants of Imam Kazim عليه السلام and not from the descendants of Ismail as some have thought and it is because Imam Sadiq عليه السلام has accompanied his statement with an oath. He knew that some would start believing that Mahdi عليه السلام is from the descendants of Ismail; therefore he negated this invalid view, so that every kind of doubt and suspicion is removed in this regard.
