Ziyad sent Abu Burdah bin Abi Musa (may Allah be pleased with him) over some charities and said: "I place you and myself in the position of a guardian of an orphan regarding this wealth: whoever is rich should abstain, and whoever is poor may eat according to what is customary. If you come across any shighar (exchange marriage), then reject it, and do not approach any woman whom her guardian is withholding until you marry her to someone of her own people who is her equal."
