An-Nisa · 4:65

65. What these hypocrites claim is not true. Allah swears by Himself that they will not have real faith until they refer for judgements to the Messenger, during his lifetime, and to the sacred law after his death, in every disagreement between them, and are happy with the Messenger’s ruling, without feeling hatred about it, or doubting it, and accepting it completely and faithfully, outwardly and inwardly.
