مَنْ فَطَّرَ صَائِمًا أَوْ جَهَّزَ غَازِيًا، فَلَهُ مِثْلُ أَجْرِهِ
Translation: Whoever provides food for a fasting person to break the fast, or equips someone engaged in a lawful religious expedition, is promised a reward like theirs.
Source: البيهقي
فَطَّرَ صَائِمًا means “provided a fasting person with the means to break the fast.” فَطَّرَ is a Form II verb with a causative sense. جَهَّزَ means “equipped or prepared,” and فَلَهُ مِثْلُ أَجْرِهِ means “the helper also has a reward like theirs.”
The narration encourages appropriate assistance in good deeds. Offering food or water for ifṭār supports worship. Its other clause concerns lawful, accountable assistance within religious limits, not blanket authorization for any armed undertaking.
