Most hadiths quoted by Shi’is and Sunnis suggest that when the verse of guardianship was revealed the Commander of the Faithful (pbuh), while in bowing, gave his ring to a poor. This specifies the primary and definitive referent of the third group of the guardiansـafter God and the Holy Prophet (PBUH)ـ; and, in addition, it confirms the translation of the term wali (guardian) into “supervisor and one vested with authority”. Thus, if the relation between the verse and its occasion of revelation is confused, it will be advantageous for those who introduce suspicions. That is why some people have tried to interpret the term ruku’ (bowing) in the sense of khusu’ (humility) and thus to go in this way. In the present article, the author will review the history of this suspicion and some traces of it in the present time, and then he will show that this claim is not scientifically supported
