A man was going to `Uthmān ibn `Affān - radhiallahu 'anhu - trying to get something done for himself. However, `Uthmān didn’t pay any attention to him, nor did he look after his need. That man went to `Uthmān ibn Hunayf and complained about that to him. `Uthmān ibn Hunayf said to him, “Go and perform ablution (wudū), then go to the mosque and pray two cycles (rak`atayn) of prayer, then say: ‘O Allāh, I ask You and I approach You through your Prophet Muhammad ﷺ, the Prophet of Mercy. O Muhammad, I approach my Lord through you that my need be fulfilled,’ then mention your need. Thereafter come to me that I might go with you.”
Then the man went away and did what he was told. After that he went to the door of `Uthmān ibn `Affān; whereupon the doorkeeper took him by the hand and ushered him into `Uthmān ibn `Affān who sat him down beside him on his mat and said to him, “What can I do for you?” He told him what he needed and `Uthmān had that done for him and then he said to him, “I didn’t remember your problem until now. Whenever you need anything come to me.” Thereupon the man left him and went to `Uthmān ibn Hunayf and said, “May Allāh bless you, `Uthmān wouldn’t look after me, nor even pay attention to me until you spoke to him about me.” `Uthmān ibn Hunayf replied, “I swear by Allāh that I didn’t speak to him.
Actually, I saw a blind man come to the Messenger of Allāh ﷺ and complain to him about losing his sight. The Prophet ﷺ said to him, “Wouldn’t you rather show patience?” He replied, “O Messenger of Allāh, I don’t have a guide and the matter has become an ordeal for me.” The Prophet ﷺ said to him, “Go and make ablution (wudū), then pray two cycles (rak`atayn) of prayer, then make this supplication (du’ā).“ I swear by Allāh, we hadn’t gone away, nor had we remained a long time in talk when the man returned as if he had never suffered any affliction."
