عَنِ ابْنِ عُمَرَ أَنَّهُ سَمِعَ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ يَقُولُ: ((لِجَهَنَّمَ سَبْعَةُ أَبْوَابٍ، بَابٌ مِنْهَا لِمَنْ سَلَّ سَيْفَهُ عَلَى أُمَّتِي)) أَوْ قَالَ: ((أُمَّةِ مُحَمَّدٍ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ))
It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that the Noble Prophet (peace and blessings be upon him and his family) said: Hell has seven gates, one of which is for the one who unsheathed the sword against my Ummah.
