The Prophet (ﷺ) said: Abraham did not tell lies except three. (One of them was) when Abraham passed by a tyrant and (his wife) Sara was accompanying him (Abu Huraira then mentioned the whole narration and said:) (The tyrant) gave her Hajar. Sara said, "Allah saved me from the hands of the Kafir (i.e. infidel) and gave me Hajar to serve me." (Abu Huraira added:) That (Hajar) is your mother, O Banu Ma'-As-Sama' (i.e., the Arabs).
Sahih al-Bukhari Book 67, Hadith 22
← Previous Hadith Allah's Messenger (ﷺ) said, any man who has a slave girl whom he educates properly, teaches good manners, manumits and marries her, will get a double reward And if any man of the people of the Scriptures believes in his own prophet and then believes in me too, he will (also) get a double reward And any slave who fulfills his duty to his master and to his Lord, will (also) get a double reward."

Sahih al-Bukhari Book 67, Hadith 21 Next Hadith → The Prophet (ﷺ) stayed for three days between Khaibar and Medina, and there he consummated his marriage to Safiyya bint Huyai. I invited the Muslims to the wedding banquet in which neither meat nor bread was offered. He ordered for leather dining-sheets to be spread, and dates, dried yoghurt and butter were laid on it, and that was the Prophet's wedding banquet. The Muslims wondered, "Is she (Saffiyya) considered as his wife or his slave girl?" Then they said, "If he orders her to veil herself, she will be one of the mothers of the Believers; but if he does not order her to veil herself, she will be a slave girl. So when the Prophet (ﷺ) proceeded from there, he spared her a space behind him (on his shecamel) and put a screening veil between her and the people.
