One day, Umayyah bin Khalaf had Hazrat Abu Fukaihah (radhiyallahu ‘anhu) pinned on the scorching ground and was busy throttling him when Umayyah bin Khalaf’s brother, Ubayy bin Khalaf, happened to pass by. Instead of this heartless man taking pity on Hazrat Abu Fukaihah (radhiyallahu ‘anhu), he urged his brother to throttle him even more. He thus throttled him so ruthlessly that people thought that he would not survive.
Fortunately, Hazrat Abu Bakr (radhiyallahu ‘anhu) happened to pass by and observed what was happening. He purchased Hazrat Abu Fukaihah (radhiyallahu ‘anhu) and set him free.
