Arabic (Original)
وَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ لَا يَمْشِيَنَّ أَحَدُكُمْ إِلَى أَخِيهِ بِالسِّلَاحِ فَإِنَّهُ لَا يَدْرِي أَحَدُكُمْ لَعَلَّ الشَّيْطَانَ يَنْزِعُ فِي يَدِهِ فَيَقَعُ فِي حُفْرَةٍ مِنْ نَارٍ.
English Translation
The Messenger of Allah (peace be upon him) said: 'None of you should walk toward his brother carrying a weapon, for none of you knows — perhaps Shaytan may cause his hand to slip, and he would fall into a pit of Fire.'
