Sayyiduna Abu al-Darda' (may Allah be pleased with him) says: "Whatever you find objectionable in your times is the change in your own deeds. If it is good, how wonderful! And if it is bad, then what a pity!" I heard your Prophet (peace and blessings be upon him) say it like this.
Al-Tabarani recorded it, and its chain is hasan (good).
