To his governor in Basra
Nahj al-Balāgha|Volume 1|Book 2|Chapter 18
وَقَدْ بَلَغَنِي تَنَمُّرُكَ لِبَنِي تَمِيم، وَغِلْظَتُكَ عَلَيْهِمْ، وَإِنَّ بَنِي تَمِيم لَمْ يَغِبْ لَهُمْ نَجْمٌ إِلَّا طَلَعَ لَهُمْ آخَرُ، وَإِنَّهُمْ لَمْ يُسْبَقُوا بِوَغْم فِي جَاهِلِيَّة وَلَا إِسْلاَم، وَإِنَّ لَهُمْ بِنَا رَحِماً مَاسَّةً، وَقَرَابَةً خَاصَّةً، نَحْنُ مَأْجُورُونَ عَلَى صِلَتِهَا، وَمَأزُورُونَ عَلَى قَطِيعَتِهَا.
I have come to know of your strictness with Banū Tamīm [1] and your harshness over them. Banū Tamīm are those that if one star sets another one rises for them. They were never exceeded in (the art of) war in pre-Islamic times or after Islam. They have a special kinship with us and a particular relationship. We shall be rewarded if we pay heed to the kinship and be deemed sinful if we disregard it.
