Nafi reported,

Ibn Umar said regarding Ibn Sayyad, "I met him twice."He continued, "I met him and said to some of his companions, 'Do you claim that he is the one?'"They answered, "No, by Allah."I said, "You have lied to me. By Allah, some of you informed me that he would not die until he became the wealthiest among you and had the most children. So that is what he is, as they claim today."Ibn Umar continued, "We talked for a while, then I parted from him. I met him another time, and his eye had become swollen and protruding."I asked, "When did your eye become as I see it?"He replied, "I do not know."I said, "You do not know, and it is in your own head?"He said, "If Allah wills, He created it in this staff of yours."Then he snorted like the loudest braying of a donkey I had ever heard. Some of my companions claimed that I struck him with a staff I had with me until it broke, but as for me, by Allah, I was not aware of it.Then he went and entered upon Umm Muiminin and told her about it.She said, "What do you want with him? Do you not know that he ﷺ said, 'The first thing that will incite him against people is an anger that will provoke him'?"In another wording, Ibn Umar met Ibn Saaid on one of the roads of Medina and said something to him that angered him. He swelled up until he filled the lane. Ibn Umar then went in to Hafsah, who had already heard about it.She said to him, "May Allah have mercy on you. What did you want from Ibn Saaid? Do you not know that the Messenger of Allah ﷺ said, 'He will only emerge as a result of an anger that provokes him'?"

عن نافع أنه كان يقول

ابن صياد، قال: قال ابن عمر: لقيته مرتين، قال: فلقيته، فقلت لبعضهم: هل تحدثون أنه هو؟ قال: لا والله، قال: قلت: كذبتني والله لقد أخبرني بعضكم أنه لن يموت حتى يكون أكثركم مالا وولدا، فكذلك هو زعموا اليوم، قال: فتحدثنا ثم فارقته، قال: فلقيته لقية أخرى وقد نفرت عينه، قال: فقلت: متى فعلت عينك ما أرى؟ قال: لا أدري، قال: قلت: لا تدري وهي في رأسك؟ قال: إن شاء الله خلقها في عصاك هذه، قال: فنخر كأشد نخير حمار سمعت، قال: فزعم بعض أصحابي أني ضربته بعصا كانت معي حتى تكسرت، وأما أنا فوالله ما شعرت، قال: وجاء حتى دخل على أم المؤمنين فحدثها فقالت: ما تريد إليه؟ ألم تعلم أنه قد قال: إن أول ما يبعثه على الناس غضب يغضبه. وفي لفظ: لقي ابن عمر ابن صائد في بعض طرق المدينة، فقال له قولا أغضبه، فانتفخ حتى ملأ السكة، فدخل ابن عمر على حفصة، وقد بلغها، فقالت له: رحمك الله ما أردت من ابن صائد؟ أما علمت أن رسول الله ﷺ قال: إنما يخرج من غضبة يغضبها؟
