Malik related to me from Daud ibn al-Husayn from Abu Ghatafan ibn Tarif al-Muriyi that Umar ibn al-Khattab said, "If someone gives a gift to strengthen ties with a relative or as sadaqa, he cannot have it returned. If some one, however, gives a gift seeking by it favour or reward, he has his gift and can reclaim it if he does not have satisfaction from it."
