Sayyiduna Hudhayfah (may Allah be pleased with him) narrates: The Prophet (peace and blessings be upon him) said: "Sheep are a blessing, camels are a source of honour for their owners, and in the forelocks of horses there is goodness until the Day of Resurrection. Your slave is your brother, so treat him well; and if you find that he is unable to manage a task, then help him."
Imam al-Bazzar recorded it. Its chain contains a narrator, al-Hasan bin Umarah, who is da'if (weak).
