Maʿānī al-ʾAkhbār > The meaning of the saying of the Prophet, Allah’s blessings be upon him and his Family, with regards to the matter of the Arabian who came to him: «O Ali, stand up and cut his tongue»
Hadith #1

أبي - رحمه الله - قال: حدثنا محمد بن يحيى، عن محمد بن أحمد، عن موسى بن عمر عن موسى بن بكر، عن رجل، عن أبي عبد الله عليه السلام قال: أتى النبي صلى الله عليه وآله أعرابي فقال له: ألست خيرنا أبا واما وأكرمنا عقبا ورئيسنا في الجاهلية والاسلام؟ فغضب النبي صلى الله عليه وآله وقال: يا أعرابي كم دون لسانك من حجاب؟ قال: اثنان: شفتان وأسنان، فقال:النبي صلى الله عليه وآله: فما كان في أحد هذين ما يرد عنا غرب لسانك هذا؟! أما إنه لم يعط أحد في دنياه شيئا هو أضر له في آخرته من طلاقة لسانه! يا علي قم فاقطع لسانه فظن الناس أنه يقطع لسانه فأعطاه دراهم.

1. My father, may Allah grant him mercy, said: We were told by Muhammed bin Yahya, from Muhammed bin Ahmad, from Musa bin Umar, from Musa bin Bikr, from a man, from Abu Abdillah, peace be upon him, that he said: An Arabian came to the Prophet, Allah’s blessings be upon him and his Family, and said to him: Are you not the best of us, in terms of father and mother, the most generous among us in terms of progeny and our leader during the Jahiliya and Islam? Then the Prophet, Allah’s blessings be upon him and his Family, was angered and said: O Arabian, how many covers are before your tongue? He said: Two lips and teeth. Then the Prophet, Allah’s blessings be upon him and his Family, said: So, where there not in any of these two what repels the wandering of this tongue of yours? Verily, none has, indeed, been given anything in this life of his that is more harmful to him in his afterlife than the unrestraintness of his tongue. O Ali, stand up and cut his tongue! Then the people assumed that he will cut his tongue, but (instead) he gave him dirhams.
