Those who believe in Imamat in the sense of spiritual Wilayat say that this tradition shows that a man who is not under the care of a perfect wali (guardian) is just like him who died in pre-Islamic days. As this tradition is a mutawatir hadith (reported by continuity of numerous authorities) we mentioned it first so that you may keep it in mind while we discuss the question of Imamat further. Now we look at the verses of the Qur'an.
Imamat in the Holy Qur'an Several verses of the Qur'an are cited by the Shi'ah in connection with Imamat. One of them is the verse which begins with the words, "Your guardian can be only Allah". Incidentally in all these cases there exist Sunni traditions which support the Shi'ah point of view.
In the Qur'an this verse runs as follows: "Your guardian can be only Allah and His messenger and those who believe, who establish prayers, pay the zakat while bowing." (Surah Mai'dah, 5:55) The word used in this verse is Wali, which means a guardian. Hence Wilayat means guardianship. According to the teachings of Islam zakat is not paid while bowing in prayers. Hence the payment of zakat while bowing cannot be called a general rule applicable to many individuals.
This verse refers to a particular incident, which took place only once and which has been reported both by the Shi'ah and the Sunnis. Once Imam Ali was bowing while offering prayers when a beggar appeared and began to ask for alms. Imam Ali beckoned and called his attention to his finger. The beggar promptly drew Imam Ali's ring from his finger and left the place. In other words Imam Ali did not wait till his prayers were finished.
He was so particular to give alms, that while he was still praying he told the beggar by gesture that he might pull out his ring, sell it and spend the money to meet his needs. Both the Shi'ah and the Sunnis agree that Imam Ali did so, and that this verse was revealed on this occasion. It may be noted that giving alms while bowing in prayers is not included in the teachings of Islam. It is neither an obligatory nor a commendable act.
Hence it cannot be said that several persons might have done so. Therefore (those who do so) is an obvious reference to Imam Ali. The Qur'an at several places has used the expression, 'they say. . .', while that thing was said by only one individual. Here also 'those who do so' means the individual who did so. Therefore by means of this verse Imam Ali was appointed the guardian of the people.
