Narrated Alqama:
I went to Sham (and asked. "Who is here?"), The people said, "Abu Ad-Darda." Abu Darda said, "Is the person whom Allah has protected against Satan, (as Allah's Apostle said) amongst you". The sub-narrator, Mughira said that the person who was given Allah's Refuge through the tongue of the Prophet was 'Ammar (bin Yasir).
