Hazrat Uwais Qarni (rahimahullah) was a famous Taabi’ee who was well known to be the best of Taabi‘een (i.e. those who met the Sahaabah (radhiyallahu ‘anhum), the companions of Rasulullah (sallallahu ‘alaihi wasallam)).

He lived during the era of Rasulullah (sallallahu ‘alaihi wasallam), but because he had to take care of his mother, he could not meet Rasulullah (sallallahu ‘alaihi wasallam). Rasulullah (sallallahu ‘alaihi wasallam) himself mentioned that Hazrat Uwais Qarni (rahimahullah) was the best of Taabi’een. Rasulullah (sallallahu ‘alaihi wasallam) also mentioned that if Hazrat Uwais Qarni (rahimahullah) had to take an oath that something would happen, then Allah Ta‘ala would make sure that it happened, and if anyone had the chance of meeting him, then he should ask him to make du‘aa for his forgiveness
