522. hadíth
وَ رَوَى مِهْرَانُ بْنُ مُحَمَّدٍ عَنِ اَلصَّادِقِ عَلَيْهِ اَلسَّلاَمُ أَنَّهُ قَالَ: «إِنَّ اَلْمَيِّتَ إِذَا مَاتَ بَعَثَ اَللَّهُ عَزَّ وَ جَلَّ مَلَكاً إِلَى أَوْجَعِ أَهْلِهِ عَلَيْهِ فَمَسَحَ عَلَى قَلْبِهِ فَأَنْسَاهُ لَوْعَةَ اَلْحُزْنِ لَوْ لاَ ذَلِكَ لَمْ تُعْمَرِ اَلدُّنْيَا.
it was narrated from Mehran ibn Muhammad that Imam Jafar ibn Muhammad Al-Sadiq (a.s) said: "When a person dies, Allah (swt), the Exalted and Glorious, sends an angel to the one among their family who is most deeply affected by the loss. The angel touches their heart and alleviates the intensity of grief. If it were not for this, the world would not be able to continue”.
