Hadith 8634ـ عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ خَالِدٍ عَنْ أَبِيهِ عَنْ وَهْبٍ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ الْسَّلام) قَالَ قَالَ رَسُولُ الله (صلّى اللهُ عَلَيْهِ وَآلِه) مَنْ عَزَّى مُصَاباً كَانَ لَهُ مِثْلُ أَجْرِهِ مِنْ غَيْرِ أَنْ يَنْتَقِصَ مِنْ أَجْرِ الْمُصَابِ شَيْءٌ.
4. A number of our people have narrated from Ahmad ibn Muhammad ibn Khalid from his father from Wahab who has said the following: “Abu ‘Abd Allah (a.s.), has said that the Messenger of Allah has said, ‘Whoever offers condolences to a person who is suffering sorrow and grief due to the death of his son, will receive a reward equal to that for the affected party without any reduction in the reward for the later mentioned.’”
