وَعَنْ بُرَيْدَةَ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «مَنْ حَلَفَ بِالْأَمَانَةِ فَلَيْسَ منا» . رَوَاهُ أَبُو دَاوُد
Buraida reported God’s Messenger as saying, “He who swears by faithfulness* is not one of our number.” Abu Dawud transmitted it. * Amana. It is held that the objection is due to the fact that the word is not the name of one of God's attributes, but merely one of the duties prescribed to mankind. It is an unsuitable word because its use suggests that it is being equated with one of God’s attributes.
