Chapter on the Virtue of Children
Man Lā Yaḥḍuruh al-Faqīh|Volume 3|Book 3|Chapter 49
وَ رُوِيَ: "أَنَّ مَنْ مَاتَ بِلاَ خَلَفٍ فَكَأَنْ لَمْ يَكُنْ فِي اَلنَّاسِ وَ مَنْ مَاتَ وَ لَهُ خَلَفٌ فَكَأَنْ لَمْ يَمُتْ".
It is narrated: "Whoever dies without leaving behind a successor, it is as if he was never among the people. And whoever dies and leaves behind a successor, it is as if he never died."
