2. Distortion by Al-Bukhari in a narration where a companion was involved in selling Wine.

Abdullah bin Zubair Al-Humaydi (Died 269 AH) narrated : 

ثنا سفيان، ثنا عمرو بن دينار، قال: أخبرني طاوس سمع ابن عباس يقول: بلغ عمر بن الخطاب أن سمرة باع خمراً فقال: قاتل الله سمرة، ألم يعلم أن رسول الله قال:  لعن الله اليهود حرمت عليهم الشحوم فجملوها فباعوها

Narrated by Ibn Abbas :

This news reached ‘Umar that Samura had sold wine, whereupon he said: May Allah destroy Samura; does he not know that Allah’s Messenger (ﷺ) said: “Let there be the curse of Allah upon the Jews that fat was declared forbidden for them, but they melted it and then sold it” ?

Musnad Al-Humaydi – Abdullah Al-Humaydi // Volume 1 // Page 9 // Number 13 // Edn. Dar ul Kutub Al-Illmiyah Beriut Lebanon.

Now when the student of Al-Humaydi ” Muhammad bin Ismael Al-Bukhari ” narrates the same tradition from Al-Humaydi, He tampers with the narration and hide the name of Companion like this : 

حدثنا الحميدي، حدثنا سفيان، حدثنا عمرو بن دينار، قال: أخبرني طاوس، أنه سمع ابن عباس رضي الله عنهما، يقول: بلغ عمر بن الخطاب أن فلاناً باع خمراً، فقال: قاتل الله فلاناً، ألم يعلم أن رسول الله صلى الله عليه وسلم قال: قاتل الله اليهود حرمت عليهم الشحوم، فجملوها فباعوها.

Narrated by Ibn Abbas :

This news reached ‘Umar that someone had sold wine, whereupon he said: May Allah destroy Someone; does he not know that Allah’s Messenger (ﷺ) said: “Let there be the curse of Allah upon the Jews that fat was declared forbidden for them, but they melted it and then sold it” ?
