Explanation

Az-Zubayr ibn ‘Adiyy, along with a group of people, went to Anas ibn Mālik (may Allah be pleased with him) who was the servant of the Messenger of Allah (may Allah's peace and blessings be upon him) to complain to him about their suffering at the hands of Al-Hajjāj ibn Yūsuf Ath-Thaqafi. Al-Hajjāj was a governor appointed by the Caliphs of Banu Umayyah, and he was notorious for oppressing people and shedding their blood, as well as for being tyrannical and stubborn. So Anas (may Allah be pleased with him) ordered them to be patient in the face of the oppression of those in authority, and informed them that no time would come upon them but the time following it would be worse until they meet their lord, and that he had heard this from the Messenger of Allah (may Allah's peace and blessings be upon him). Evil is not always a general absolute evil; it could be evil in some situations and good in others.
