Mukhtasar Muslim

´Sayyiduna Abu Hurairah (may Allah be pleased with him) says that` I heard the Messenger of Allah (peace and blessings be upon him) say: "All of my Ummah will be forgiven except those who disclose (their sins), and disclosing is that a person commits a (bad) deed at night, and when morning comes, Allah has concealed that (bad deed), but he himself says, 'O so-and-so! Last night I did such-and-such (bad) deed,' even though he committed the bad deed at night (and) Allah had concealed it. At night, the Lord conceals, and in the morning, this (person) removes Allah's covering."
