Nabi Pakﷺ telling first to die after him:
Imâm al-Bukhârî narrated on the authority of ‘Âishah (may Allâh be pleased with her) that: Some of the wives of the Prophet ﷺ asked him: “Who amongst us will be the first to follow you (i.e. die after you)?” He said: “Whoever has the longest hand.” So, they started measuring their hands with a
stick and Sauda’s hand turned to be the longest. (When Zainab bint Gahsh died first of all in the Caliphate of ‘Umar). We came to know that the long hand was a symbol of practicing charity, so she was the first to follow the Prophet ﷺ and she used to love to practice charity. (Sauda died later during the Caliphate of ‘Umar).
Nabi Pakﷺ telling about the merits of Uwais alQuranî:
Imâm Muslim narrated on the authority of Usaid bin Jâbir that : “A delegation from Kûfah came to ‘Umar and there was a person amongst them who jeered at Uwais. Thereupon ‘Umar said: “Is there amongst us one from Qarân?” That persom came and ‘Umar said: “Verily, Allâh’s Messenger ﷺ has said: “There would come to you a person from Yemen, who would be called Uwais and he would leave none in Yemen (behind him) except his mother, and he would have whiteness (due to leprosy) and he supplicated Allâh and it was cured except for the size of a dînâr or dirham. He who amongst you meets him should ask him to supplicate for forgiveness (from Allâh) for you. “”
In another narration by Imâm Muslim, ‘Umar said: “I heard Allâh’s Messenger ﷺ saying: “Worthy amongst the successors would be a person who would be called Uwais. He would have his mother (living with him) and he would have (a small) sign of leprosy. Ask him to supplicate Allâh for you, for forgiveness. “94
This man actually existed at the time of the Caliphate of ‘Umar, in exactly the same description as the Prophet ﷺ told the companions. Many narrations described the white mark, which existed on his body, and said that he had been extremely kind to his mother. ‘Umar met him, and asked him about his disease and asked him to supplicate Allâh for him, for forgiveness.
