was narrated that ‘Umar bin al-Khattab ؓ said: The Messenger of Allah ﷺ said: “Whoever shades the head of a warrior, Allah will shade him on the Day of Resurrection; whoever equips a warrior until he is fully equipped, will have a reward like his; whoever builds a mosque in which the Name of Allah is mentioned. Allah will build for him a house in Paradise.” (Using translation from Aḥmad 376)
قَالَ رَسُولُ اللَّهِ ﷺ «مَنْ أَظَلَّ رَأْسَ غَازٍ أَظَلَّهُ اللَّهُ يَوْمَ الْقِيَامَةِ وَمَنْ جَهَّزَ غَازِيًا حَتَّى يَسْتَقِلَّ بِجَهَازِهِ فَلَهُ مِثْلُ أَجْرِهِ»
