It is narrated from Sayyiduna Shaddad bin Aws (may Allah be pleased with him) that Sayyiduna Abu Dharr (may Allah be pleased with him) would hear a hadith from the Messenger of Allah (peace and blessings be upon him) in which there was a strict command. After hearing this hadith, he would go to his people so that he could enforce strictness upon them in light of this hadith. Later, the Messenger of Allah (peace and blessings be upon him) would grant concession and leniency in that command. However, Sayyiduna Abu Dharr (may Allah be pleased with him) would not hear about this leniency and concession, so he would continue to adhere to the strict command.
