Man Lā Yaḥḍuruh al-Faqīh|Volume 1|Book 1|Chapter 28
وَقَالَ عَلَيْهِ اَلسَّلاَمُ: «مَا مِنْ عَبْدٍ يَمْسَحُ يَدَهُ عَلَى رَأْسِ يَتِيمٍ تَرَحُّماً لَهُ إِلاَّ أَعْطَاهُ اَللَّهُ عَزَّ وَ جَلَّ بِكُلِّ شَعْرَةٍ نُوراً يَوْمَ اَلْقِيَامَةِ.
Imam Jafar ibn Muhammad Al-Sadiq عليه السلام said: "There is no servant who passes their hand over the head of an orphan out of compassion for them except that Allah سبحانه وتعالى, the Mighty and Majestic, grants them a light for every strand of hair (they touch) on the Day of Judgment."
