Sahih Bukhari Volume 9, Book 92, Hadith 7059

حَدَّثَنَا مُحَمَّدُ بْنُ عَرْعَرَةَ، حَدَّثَنَا شُعْبَةُ، عَنْ قَتَادَةَ، عَنْ أَنَسِ بْنِ مَالِكٍ، عَنْ أُسَيْدِ بْنِ حُضَيْرٍ، أَنَّ رَجُلاً، أَتَى النَّبِيَّ صلى الله عليه وسلم فَقَالَ يَا رَسُولَ اللَّهِ اسْتَعْمَلْتَ فُلاَنًا وَلَمْ تَسْتَعْمِلْنِي‏.‏ قَالَ ‏"‏ إِنَّكُمْ سَتَرَوْنَ بَعْدِي أَثَرَةً، فَاصْبِرُوا حَتَّى تَلْقَوْنِي ‏"‏‏.

Narrated By Usaid bin Hudair : A man came to the Prophet and said, "O Allah's Apostle! You appointed such-and-such person and you did not appoint me?" The Prophet said, "After me you will see rulers not giving you your right (but you should give them their right) and be patient till you meet me."
