"An-Nu'man ibn Bashir said, "I heard the Messenger of Allah, may Allah bless him and grant him peace, say, "The halal is clear and the haram is clear. But between the two there are doubtful things about which most people have no knowledge. Whoever exercises caution with regard to what is doubtful, shows prudence in respect of his deen and his honour. Whoever gets involved in the doubtful things is like a herdsman who grazes his animals near a private preserve . He is bound to enter it. Every king has a private preserve and the private preserve of Allah on His earth are the things that He has made forbidden. There is lump of flesh in the body, the nature of which is that when it is sound, the entire body is sound, and when it is corrupt, the entire body is corrupt - it is the heart."

“Abu Hurayra reported that the Messenger of Allah, may Allah bless him and grant him peace, said, "There are three people that Allah will not speak to on the Day of Rising nor purify nor look at and they will have a painful punishment: an old adulterer, a lying ruler and a poor person who is arrogant.”
