Sayyiduna Abu Huraira (may Allah be pleased with him) said: I heard the Messenger of Allah (peace and blessings of Allah be upon him) say: "When Allah created mercy, He created it in one hundred parts. He kept ninety-nine parts with Himself and sent one part to the entire creation. So if the disbelievers knew all the mercy that is with Allah, they would never despair of Paradise (despite their disbelief, polytheism, etc.), and if the believers knew all the punishment that is with Allah, they would never feel safe from Hell (despite their faith, belief, and righteous deeds)."
