Majma al-Zawaid — Hadith 384

Sayyiduna Imran bin Husayn (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "What is your opinion about the fornicator, the thief and the one who drinks wine?" The people said: "Allah and His Messenger know best." The Prophet (peace and blessings be upon him) said: "These are shameful deeds, and there is a punishment for them. But shall I not tell you about the greatest of the major sins? (They are:) associating partners with Allah." Then the Prophet (peace and blessings be upon him) recited this verse: "Whoever associates partners with Allah has indeed fabricated a tremendous sin." "(And the second great sin) is disobedience to parents." Then he recited this verse: "Be grateful to Me and to your parents; to Me is the final return." (The narrator states:) The Prophet (peace and blessings be upon him) was sitting reclining; he (peace and blessings be upon him) sat up straight and said: "Beware! And false speech too (is among the major sins)." Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) says: "Everything that Allah Almighty has forbidden, (committing it) counts as a major sin."
Tabarani recorded it in al-Mu'jam al-Kabir, and its narrators are thiqat (trustworthy), except that the narrator al-Hasan is a mudallis (one who conceals defects in the chain), and he narrated this with 'an'anah (using the word 'from' without stating that he heard it).
