الحسن بن علي عن أبي الحسن عليه السلام قال: سمعته يقول: إن الرجل ليكون قد بقي من اجله ثلاثون سنة فيكون وصولا لقرابته وصولا لرحمه فيجعلها الله ثلاثة وثلثين سنة وانه ليكون قد بقي من اجله ثلاثة (وثلاثون) سنة فيكون عاقا لقرابته قاطعا لرحمه فيجعلها الله ثلاثين سنة .
27.Al-Ḥasan narrated from ʿAlī, from Abū al-Ḥasan  whom he heard saying, “It may be that thirty years remain for a man to live, but he regularly keeps ties with his close kinsfolk and with his near relatives, so Allah increases it to thirty-three years. And it may be that thirty three years remain of his life, but he is undutiful towards his close kinsfolk and cuts off ties with his near relatives, so Allah reduces it to thirty years.”[1]
