It is narrated from Sayyidah Umm al-Hakam (may Allah be pleased with her) that she said: The Messenger of Allah (peace and blessings be upon him) returned from an expedition, and he (peace and blessings be upon him) had obtained some slaves. My sister and I went to Sayyidah Fatimah (may Allah be pleased with her), then we went to the Messenger of Allah (peace and blessings be upon him) and asked him to grant us something especially, and we mentioned our needs. He (peace and blessings be upon him) said: "The orphans of the people of Badr have come before you."
