‘Uthman b. Hunaif told that a blind man came to the Prophet (ﷺ) and asked him to pray to God to cure him. He replied, “If you wish, I shall make supplication to God, but if you wish you will endure, for that is better for you." The man asked him to make supplication. [‘Uthman] said

He then commanded him to perform ablution, doing it well, and make this supplication, “O God, I make request of Thee and I turn towards Thee by means of Thy Prophet Muhammad , the prophet of mercy. By means of you 1 have turned towards my Lord to accomplish for me this need of mine. O God, make him an intercessor for me.” 1. bika. This would seem here to refer to the Prophet, although by itself it might naturally be taken to refer to God. The sentence which precedes certainly suggests that it must refer to the Prophet, in which case the translation might go, “by means of whom I have turned towards my Lord.” Changes of pronouns in Arabic often present difficulties to the translator. Tirmidhi transmitted it, saying this is a hasan sahih gharib tradition.
