The Companions of the Prophet ﷺ told us that they were travelling with the Prophet ﷺ. A man of them slept, and one of them went to the rope which he had with him. He took it, by which he was frightened. The Prophet ﷺ said: It is not lawful for a Muslim that he frightens a Muslim. (Using translation from Abū Dāʾūd 5004)
حَدَّثَنَا أَصْحَابُ مُحَمَّدٍ ﷺ أَنَّهُمْ كَانُوا يَسِيرُونَ مَعَ النَّبِيِّ ﷺ فَنَامَ رَجُلٌ مِنْهُمْ فَانْطَلَقَ بَعْضُهُمْ إِلَى أَحْبُلٍ مَعَهُ فَأَخَذَهَا فَفَزِعَ فَقَالَ رَسُولُ اللهِ ﷺ لَا يَحِلُّ لِمُسْلِمٍ أَنْ يُرَوِّعَ مُسْلِمًا
