حَدَّثَنِي عَبْدُ اللَّهِ بْنُ مُحَمَّدٍ، حَدَّثَنَا سُفْيَانُ، عَنْ عَمْرٍو، عَنْ جَابِرٍ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ ‏"‏ مَنْ لِكَعْبِ بْنِ الأَشْرَفِ ‏"‏‏.‏ فَقَالَ مُحَمَّدُ بْنُ مَسْلَمَةَ أَتُحِبُّ أَنْ أَقْتُلَهُ قَالَ ‏"‏ نَعَمْ ‏"‏‏.‏ قَالَ فَأْذَنْ لِي فَأَقُولَ‏.‏ قَالَ ‏"‏ قَدْ فَعَلْتُ ‏"‏‏.‏

Narrated 'Abdullah bin Umar (ra): Once, Allah's Messenger accompanied by Ubai bin Ka'b set out to Ibn Saiyyad. He was informed that Ibn Saiyyad was in a garden of date palms. When Allah's Messenger entered the garden of date-palms, he started hiding himself behind the trunks of the palms while Ibn Saiyyad was covered with a velvet sheet with murmurs emanating from under it. Ibn Saiyyah's mother saw Allah's Messenger and said, "O Saf! This is Muhammad." So Ibn Saiyyad got up. Allah's Messenger said, "If she had left him (in his state), the truth would have been clear."
