حَدَّثَنَا أَبُو سَلَمَةَ الْخُزَاعِيُّ أَنْبَأَنَا لَيْثٌ وَيُونُسُ حَدَّثَنَا لَيْثٌ عَنْ يَزِيدَ بْنِ عَبْدِ اللَّهِ بْنِ أُسَامَةَ بْنِ الْهَادِ عَنِ الْوَلِيدِ بْنِ أَبِي الْوَلِيدِ عَنْ عُثْمَانَ بْنِ عَبْدِ اللَّهِ يَعْنِي ابْنَ سُرَاقَةَ عَنْ عُمَرَ بْنِ الْخَطَّابِ رَضِيَ اللَّهُ عَنْهُ قَالَ سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ مَنْ أَظَلَّ رَأْسَ غَازٍ أَظَلَّهُ اللَّهُ يَوْمَ الْقِيَامَةِ وَمَنْ جَهَّزَ غَازِيًا حَتَّى يَسْتَقِلَّ كَانَ لَهُ مِثْلُ أَجْرِهِ حَتَّى يَمُوتَ قَالَ قَالَ يُونُسُ أَوْ يَرْجِعَ وَمَنْ بَنَى لِلَّهِ مَسْجِدًا يُذْكَرُ فِيهِ اسْمُ اللَّهِ تَعَالَى بَنَى اللَّهُ لَهُ بِهِ بَيْتًا فِي الْجَنَّةِ
مسند امام احمد بن حنبل · Hadith 126
It was narrated from 'Uthman bin 'Abdullah, i.e. Ibn Suraqah, that 'Umar bin al-Khattab said: I heard the Messenger of Allah 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."
