The Sufficient (Vol 7) · Hadith 203 (#Ḥadīth #6)

6- عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنْ هَارُونَ بْنِ مُسْلِمٍ عَنْ مَسْعَدَةَ بْنِ صَدَقَةَ عَنْ أَبِي عَبْدِ اللهِ قَالَ مَنْ عَدَلَ فِي وَصِيَّتِهِ كَانَ بِمَنْزِلَةِ مَنْ تَصَدَّقَ بِهَا فِي حَيَاتِهِ وَمَنْ جَارَ فِي وَصِيَّتِهِ لَقِيَ اللهَ عَزَّ وَجَلَّ يَوْمَ الْقِيَامَةِ وَهُوَ عَنْهُ مُعْرِضٌ.

6. Ali ibn Ibrahim has narrated from his father from Harun ibn Muslim from Mas’adah ibn Sadaqah who has narrated the following: “Abu ‘Abd Allah , has said, ‘One who maintains justice in his will is like one who has given in charity in his lifetime and one who is unjust in his will he, on the Day of Judgment, will come before Allah, most Majestic, most Glorious, who will shun him.’”
