“The story of Uwais Al-Qarni was mentioned in Sahih Muslim as well as in other books. Now even though he was from the Tabi’een and did not see the Messenger [Salah Allahu Alaihi wa salam], the Messenger [Salah Allahu Alaihi wa salam] had advised ‘Umar ibn Al-Khatab [Radiya Allahu ‘Anhu] that if he meets [Uwais] then he, ‘Umar, should ask [Uwais] to ask Allah to forgive him and to make supplication for him.
Asir ibn Jaabir radhiallahu `anhu narrated:
Whenever people would come from Yemen, `Umar radhiallahu `anhu would ask them, “Is Uways Al-Qaranee amongst you?” until, one year, he met Uways.
He said, “Are you Uways Al-Qaranee?” He said, “Yes.”
`Umar continued, “From Muraad, then Qaran?” He said, “Yes.”
`Umar then asked, “Were you once afflicted with leprosy and your skin healed except for a dirham’s area?” Uways said, “Yes.”
`Umar finally asked, “Do you have a mother (that is alive)?” He said, “Yes.”
`Umar then said, “I heard the Messenger of Allah – sallallahu `alayhi wa sallam – say, ‘Uways ibn Aamir will come to you with the delegations from Yemen, from Muraad, then from Qaran. He was once afflicted with leprosy and his skin healed except for a dirham’s area. He has a mother, and he treats her kindly. If he was to ever swear by Allah (for something) Allah would fulfill his oath. If you can, request that he ask forgiveness for you.”
`Umar then requested from Uways, “Ask forgiveness for me.” And Uways Al-Qaranee did.
