Malik :: Book 56 : Hadith 56.2.6
Malik related to me from Abdullah ibn Dinar that Abu Salih as-Samman informed him that Abu Hurayra said, "Truly a man utters words to which he attaches no importance, and by them he falls into the fire of Jahannam, and truly a man utters words to which he attaches no importance, and by them Allah raises him into the Garden."
