كتاب الأيمان والنذور
Read the English translation first, with the original Arabic directly underneath.
Narrated `Abdur-Rahman bin Samura:
The Prophet (ﷺ) said, "O `Abdur-Rahman bin Samura! Do not seek to be a ruler, because if you are given authority for it, then you will be held responsible for it, but if you are given it without asking for it, then you will be helped in it (by Allah): and whenever you take an oath to do something and later you find that something else is better than the first, then do the better one and make expiation for your oath."
يَا عَبْدَ الرَّحْمَنِ بْنَ سَمُرَةَ لاَ تَسْأَلِ الإِمَارَةَ، فَإِنَّكَ إِنْ أُوتِيتَهَا عَنْ مَسْأَلَةٍ وُكِلْتَ إِلَيْهَا، وَإِنْ أُوتِيتَهَا مِنْ غَيْرِ مَسْأَلَةٍ أُعِنْتَ عَلَيْهَا، وَإِذَا حَلَفْتَ عَلَى يَمِينٍ فَرَأَيْتَ غَيْرَهَا خَيْرًا مِنْهَا، فَكَفِّرْ عَنْ يَمِينِكَ، وَأْتِ الَّذِي هُوَ خَيْرٌ
