Man Lā Yaḥḍuruh al-Faqīh|Volume 4|Book 1|Chapter 84
وَ فِي رِوَايَةِ اَلْحَسَنِ بْنِ عَلِيٍّ اَلْوَشَّاءِ عَنْ حَمَّادِ بْنِ عُثْمَانَ عَنْ أَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ قَالَ: "مَنْ أَوْصَى بِالثُّلُثِ فَقَدْ أَضَرَّ بِالْوَرَثَةِ وَ اَلْوَصِيَّةُ بِالْخُمُسِ وَ اَلرُّبُعِ أَفْضَلُ مِنَ اَلْوَصِيَّةِ بِالثُّلُثِ" وَ قَالَ "مَنْ أَوْصَى بِالثُّلُثِ فَلَمْ يَتَّرِكْ".
In the narration of Al-Hasan ibn Ali Al-Washsha' from Hammad ibn Uthman from Abu Abdullah Imam Jafar ibn Muhammad Al-Sadiq عليه السلام, that he said: "Whoever bequeaths one-third has harmed the heirs. Bequeathing one-fifth or one-fourth is better than bequeathing one-third." Imam عليه السلام also said: "Whoever bequeaths one-third without leaving anything behind has gone to excess."
