وَعَنِ ابْنِ مَسْعُودٍ رَضِيَ اللَّهُ عَنْهُ قَالَ بَيْنَمَا نَحْنُ مَعَ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ نَمْشِي إِذْ مَرَّ بِصِبْيَانٍ يَلْعَبُونَ فِيهِمْ ابْنُ صَيَّادٍ فَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ ”تَرِبَتْ يَدَاكَ أَتَشْهَدُ أَنِّي رَسُولُ اللَّهِ“ فَقَالَ هُوَ أَتَشْهَدُ أَنِّي رَسُولُ اللَّهِ قَالَ فَقَالَ عُمَرُ رَضِيَ اللَّهُ عَنْهُ دَعْنِي فَلَا أَضْرِبَ عُنُقَهُ قَالَ فَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ ”إِنْ يَكُ الَّذِي تَخَافُ فَلَنْ تَسْتَطِيعَهُ“
It is narrated from Sayyiduna Abdullah bin Masood (may Allah be pleased with him), he says: We were going with the Messenger of Allah (peace and blessings be upon him), and the Messenger of Allah (peace and blessings be upon him) passed by some children who were playing, and among them was Ibn Sayyad. The Messenger of Allah (peace and blessings be upon him) said to him: "May your hands be dusted! Do you bear witness that I am the Messenger of Allah?" In response, he said: "And do you bear witness that I am the Messenger of Allah?" Seeing this situation, Sayyiduna Umar (may Allah be pleased with him) said: "O Messenger of Allah! Allow me to kill him?" The Messenger of Allah (peace and blessings be upon him) said: "If he is the same Dajjal about whom you are apprehensive, then you will never be able to kill him."
