Excerpt from 'An Enlightening Commentary into the Light of the Holy Quran vol. 4':
'Verily, verily your guardian (waliyy) is only Allah and His Messenger and those who believe, those who establish prayer and pay the poor-rate while bowing down (in prayer).' [5:55]
It has been cited in the occasion of revelation of the above verse that a beggar entered the Mosque of the Messenger of Allah (S) and asked people for a charity. Nobody gave him anything. Ali-Ibn-Abi- talib (as) pointed his finger to him while he was bowing in the prayer, and he (as) remitted his ring to that beggar. In honouring of this remittal, the above verse was revealed.
The explanation of the above event has been narrated by ten people among the companions of the Prophet (S), like: Ibn-Abbas, 'Ammar, Jabir-ibn-' Abdillah, 'Abuthar, 'Anas-ibn-Malik, Bilal, and so on. The scholars of both schools of Sunni and Shi'ah have confirmed this occasion of revelation.
