Sayyiduna Sahl bin Hunayf (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "Whoever helps a person striving in the path of Allah, or helps a debtor in hardship, or helps a mukatab slave (one who has contracted to buy his freedom), Allah Almighty will grant him His shade on the Day when there will be no shade except His shade."
Ahmad recorded it; its chain contains a narrator, Abdullah bin Sahl bin Hunayf, whom I do not know; the rest of its narrators are such that their hadith is hasan (good).
