Zaid bin Aslam narrates that people came to see Hazrat Abu Dujanah (ra) when he was unwell, yet his face was glowing. Someone asked him why his face was glowing, to which Hazrat Abu Dujanah (ra) replied, “From among my actions, there are two things which I adhere to strictly and are significant; firstly, I never involve myself in matters which do not concern me. Secondly, I have nothing but kindness in my heart for my fellow Muslims.”
