عَنْ زَيْدِ بْنِ خَالِدٍ الْجُهَنِيِّ رَضِيَ اللَّهُ عَنْهُ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ مَنْ جَهَّزَ غَازِيًا أَوْ خَلَفَهُ فِي أَهْلِهِ كُتِبَ لَهُ مِثْلُ أَجْرِهِ إِلَّا أَنَّهُ لَا يُنْقَصُ مِنْ أَجْرِ الْغَازِي شَيْءٌ
Narrated from Sayyiduna Zayd bin Khalid al-Juhani (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: Whoever equips a warrior (ghazi) or takes his place among his family, he will receive a reward equal to that of the warrior, while the warrior’s reward will not be diminished in the least.
