Bulugh al-Maram, Book 14, Hadith 1399 (English)

Narrated [Abu Hurairah (RA)]: Allah's Messenger said: "You will eagerly seek out the office of governorship, but it will become a cause of regret on the Day of Resurrection. How excellent it is as a Murdi'ah (wet nurse)! And how evil it is as a Fatimah (one who weans)! [Reported by al-Bukhari].

وَعَنْهُ ‏- رضى الله عنه ‏- قَالَ: قَالَ رَسُولُ اَللَّهِ ‏- صلى الله عليه وسلم ‏-{ "إِنَّكُمْ سَتَحْرِصُونَ عَلَى اَلْإِمَارَةِ, وَسَتَكُونُ نَدَامَةً يَوْمَ اَلْقِيَامَةِ, فَنِعْمَ اَلْمُرْضِعَةُ, وَبِئْسَتِ اَلْفَاطِمَةُ" } رَوَاهُ اَلْبُخَارِيُّ 1‏.‏ ‏1 ‏- صحيح.‏ رواه البخاري ( 7148 )‏.‏
