I heard the Messenger of Allah ﷺ say: “Whoever shades the head of a fighter (mujahid), Allah will shade him on the Day of Resurrection; whoever equips a fighter until he has all that he needs, will have a reward equal to his until he dies (Yoonus said: or returns); whoever builds a mosque in which the Name of Allah may He be exalted, is remembered,Allah will build for him a house in Paradise.ʿ ,
سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ مَنْ أَظَلَّ رَأْسَ غَازٍ أَظَلَّهُ اللهُ يَوْمَ الْقِيَامَةِ وَمَنْ جَهَّزَ غَازِيًا حَتَّى يَسْتَقِلَّ كَانَ لَهُ مِثْلُ أَجْرِهِ حَتَّى يَمُوتَ قَالَ يُونُسُ أَوْ يَرْجِعَ وَمَنْ بَنَى لِلَّهِ مَسْجِدًايُذْكَرُ فِيهِ اسْمُ اللهِ تَعَالَى بَنَى اللهُ لَهُ بِهِ بَيْتًا فِي الْجَنَّةِ
