Mukhtasar Muslim

Narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) said: When someone says (considering himself superior and others inferior) that people are ruined, then he himself is the most ruined of all. (And if he says it out of grief or sorrow over the corruption of religion, then it is not prohibited.) Abu Ishaq (Ibn Muhammad bin Sufyan) said: I do not know whether the word in the hadith is "ahlak" or "ahlak".
