حَدَّثَنَا عُثْمَانُ بْنُ أَبِى شَيْبَةَ وَإِسْحَاقُ بْنُ إِبْرَاهِيمَ - وَاللَّفْظُ لِعُثْمَانَ - قَالَ إِسْحَاقُ أَخْبَرَنَا وَقَالَ عُثْمَانُ حَدَّثَنَا جَرِيرٌ عَنِ الأَعْمَشِ عَنْ أَبِى وَائِلٍ عَنْ عَبْدِ اللَّهِ قَالَ كُنَّا مَعَ رَسُولِ اللَّهِ -صلى الله عليه وسلم- فَمَرَرْنَا بِصِبْيَانٍ فِيهِمُ ابْنُ صَيَّادٍ فَفَرَّ الصِّبْيَانُ وَجَلَسَ ابْنُ صَيَّادٍ فَكَأَنَّ رَسُولَ اللَّهِ -صلى الله عليه وسلم- كَرِهَ ذَلِكَ فَقَالَ لَهُ النَّبِىُّ -صلى الله عليه وسلم- « تَرِبَتْ يَدَاكَ أَتَشْهَدُ أَنِّى رَسُولُ اللَّهِ ». فَقَالَ لاَ. بَلْ تَشْهَدُ أَنِّى رَسُولُ اللَّهِ. فَقَالَ عُمَرُ بْنُ الْخَطَّابِ ذَرْنِى يَا رَسُولَ اللَّهِ حَتَّى أَقْتُلَهُ. فَقَالَ رَسُولُ اللَّهِ -صلى الله عليه وسلم- « إِنْ يَكُنِ الَّذِى تَرَى فَلَنْ تَسْتَطِيعَ قَتْلَهُ ».

It was narrated that 'Abdullah said: "We were with the Messenger of Allah (s.a.w) and we passed by some boys among whom was Ibn Sayyad. The boys went away and Ibn Sayyad sat down. It was as if the Messenger of Allah (s.a.w) did not like that. The Prophet (s.a.w) said to him: 'May your hands be rubbed with dust. Do you bear witness that I am the Messenger of Allah?' He said: 'No; rather you should bear witness that I am the messenger of Allah.' 'Umar bin Al-Khattab said: 'O Messenger of Allah, let me kill him.' The Messenger of Allah (s.a.w) said: 'If he is who you think he is, you will never be able to kill him"'
