Man Lā Yaḥḍuruh al-Faqīh|Volume 1|Book 1|Chapter 26
وَ رَوَى عُمَرُ بْنُ يَزِيدَ عَنْ أَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ أَنَّهُ قَالَ: «إِذَا مَاتَ اَلْمُؤْمِنُ فَحَضَرَ جَنَازَتَهُ أَرْبَعُونَ رَجُلاً مِنَ اَلْمُؤْمِنِينَ وَ قَالُوا: اَللَّهُمَّ إِنَّا لاَ نَعْلَمُ مِنْهُ إِلاَّ خَيْراً وَ أَنْتَ أَعْلَمُ بِهِ مِنَّا قَالَ اَللَّهُ تَبَارَكَ وتَعَالَى قَدْ أَجَزْتُ شَهَادَاتِكُمْ وَ غَفَرْتُ لَهُ مَا عَلِمْتُ مِمَّا لاَ تَعْلَمُونَ.
Omar ibn Yazid narrated from Imam Jafar ibn Muhammad Al-Sadiq عليه السلام, that He said: "If a believer passes away and forty men from among the believers attend their funeral and say: Allāhumma innā lā na‘lam minhu illā khayran wa anta a‘lamu bihi minnā 'O’ Allah سبحانه وتعالى, we do not know of anything but good from this person, and You know him better than we do,' Allah سبحانه وتعالى, Blessed and Exalted, responds, 'I have accepted your testimony and forgiven him for what I know that you do not.'"
