Sahih Bukhari Volume 9, Book 92, Hadith 7070

حَدَّثَنَا مُحَمَّدُ بْنُ يُوسُفَ، حَدَّثَنَا سُفْيَانُ، عَنِ الزُّبَيْرِ بْنِ عَدِيٍّ، قَالَ أَتَيْنَا أَنَسَ بْنَ مَالِكٍ فَشَكَوْنَا إِلَيْهِ مَا نَلْقَى مِنَ الْحَجَّاجِ فَقَالَ ‏"‏ اصْبِرُوا، فَإِنَّهُ لاَ يَأْتِي عَلَيْكُمْ زَمَانٌ إِلاَّ الَّذِي بَعْدَهُ شَرٌّ مِنْهُ، حَتَّى تَلْقَوْا رَبَّكُمْ ‏"‏‏.‏ سَمِعْتُهُ مِنْ نَبِيِّكُمْ صلى الله عليه وسلم‏.

Narrated By Az-Zubair bin 'Adi : We went to Anas bin Malik and complained about the wrong we were suffering at the hand of Al-Hajjaj. Anas bin Malik said, "Be patient till you meet your Lord, for no time will come upon you but the time following it will be worse than it. I heard that from the Prophet."
