كتاب آداب القضاة
Read the English translation first, with the original Arabic directly underneath.
It was narrated that 'Abdur-Rahman bin Samurah said:
"The Messenger of Allah [ﷺ] said: 'Do not ask for governorship. For if it is given to you because of asking, you will be left to your own devices, but if it is given to you without asking, you will be helped (by Allah).'"
لاَ تَسْأَلِ الإِمَارَةَ فَإِنَّكَ إِنْ أُعْطِيتَهَا عَنْ مَسْأَلَةٍ وُكِلْتَ إِلَيْهَا وَإِنْ أُعْطِيتَهَا عَنْ غَيْرِ مَسْأَلَةٍ أُعِنْتَ عَلَيْهَا
