وَعَنْ زَيْدِ بْنِ خَالِدٍ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسلم: «من فَطَّرَ صَائِمًا أَوْ جَهَّزَ غَازِيًا فَلَهُ مِثْلُ أَجْرِهِ» . رَوَاهُ الْبَيْهَقِيُّ فِي شُعَبِ الْإِيمَانِ وَمُحْيِي السّنة فِي شرح السّنة وَقَالَ صَحِيح
Zaid b. Khalid reported God’s messenger as saying, ‘He who gives one who has been fasting something with which to break his fast, or who equips a fighter will have a reward equivalent to his.” Baihaqi transmitted it in Shu'ab al-iman, and Muhyi as-sunna, who said it is sahih, in Sharh as-sunna.
