Sayyiduna Abu Hurayrah (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "The first to race ahead into Paradise will be a slave who obeyed Allah Almighty and obeyed his masters."
Al-Tabarani recorded it in al-Mu'jam al-Awsat; its chain contains a narrator, Bashir bin Maymun Abu Sayfi, who is matruk (abandoned).
