It is related by Abdullah bin Masud that Muhammad said, “A faithful believer neither attacks with his tongue nor utters a curse nor speaks ill of anyone nor calls names.” From Tirmidhi
He was very close to Imam Bokhari. At-Tirmidhi was a pupil of al-Bukhari, who was based in Khurasan. Adh-Dhahabi wrote, “His knowledge of hadith came from al-Bukhari.”[16] At-Tirmidhi mentioned al-Bukhari’s name 114 times in his Jami`. He used al-Bukhari’s Kitab at-Tarikh as a source when mentioning discrepancies in the text of a hadith or its transmitters, and praised al-Bukhari as being the most knowledgeable person in Iraq or Khurasan in the science of discrepancies of hadith.
