Hazrat Usman bin Ubaidullah, who was the freed slave of Hazrat Sa’d bin Abi Waqqas, narrates that I saw Hazrat Ibn Umar (may Allah be pleased with them), Hazrat Abu Hurairah, Hazrat Abu Qatadah, and Hazrat Abu Usaid Sa’idi; these noble companions would pass by us while we were in the school, and we would smell the fragrance of ‘abeer’ from them, which is a perfume mixed with saffron.
