Islam regulated the relations between masters and slaves. It called for kindly treating slaves and urged masters to emancipate them. It also encouraged slaves to care for Allah's and their masters' rights, for their masters bought them so it does not make sense that their properties may be wasted. Islam makes obeying masters, for the sake of Allah, is one of the greatest acts of worship. In this hadith, Jarir ibn Abdullah narrated that if any slave flees from his masters, he is a disbeliever. It may mean that he denies his master's rights or behaves like disbelievers do. It may also mean that his behavior leads to disbelief. It does not mean the literal meaning of disbelief. It means that he disbelieves Allah's graces by fleeing from his master until he returns to him willingly or unwillingly. Allah neither pleases him nor accepts his righteous deeds until his return, repentance, and righteousness. The complete narration of this hadith is that Mansour ibn Abdurrahman (the hadith narrator on the authority of Amer Ash-Sha’by) said after his narration, "By Allah, it is a Prophetic hadith, but I hate that it may be narrated on my authority here in Basra.” This means that Mansour traced back this hadith to the companion but he then swore that it was the Prophet's hadith to let his knowledgeable companions know about that. He feared that his transmitted narration to the Prophet may have spread in Basra which was full of Kharijites and Mutazilites who believed that one would eternally remain in Hell due to his sins. The former added that he is a disbeliever, depending on the apparent meaning of this hadith. Finally, this hadith contains the following benefits: (1) The slave’s fleeing from his masters is a major sin that contradicts the faith's requirements of obeying them and (2) Muslim predecessors cautioned against the wrong concepts that people of heresies may deduce from the Islamic texts that may apparently support their heresies..
