It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) drew four lines on the ground and then asked: "Do you know what this is?" The Companions said: Allah and His Messenger know best. The Messenger of Allah (peace and blessings be upon him) said: "The best of the women of the people of Paradise are Khadijah bint Khuwaylid and Fatimah bint Muhammad (may Allah be pleased with them both)." This hadith has a sahih (authentic) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it.
