It is narrated from Sayyidah Aishah (may Allah be pleased with her) that she said: When the people of Makkah sent wealth for the ransom of their prisoners, Sayyidah Zaynab (may Allah be pleased with her), the daughter of the Messenger of Allah (peace and blessings be upon him), sent some wealth for the ransom of (her husband) Abu al-As, among which was the necklace that Sayyidah Khadijah (may Allah be pleased with her) had given Zaynab at the time of her marriage. When the Messenger of Allah (peace and blessings be upon him) saw that necklace, it deeply affected his heart and intense tenderness overcame him (peace and blessings be upon him). Then he (peace and blessings be upon him) said: "If you think it best, release Zaynab's prisoner and return her wealth to her." And the Messenger of Allah (peace and blessings be upon him) had taken a pledge from Abu al-As, and he had promised that he would send Sayyidah Zaynab to him (peace and blessings be upon him) (in Madinah). This hadith is sahih (authentic) on the condition of Muslim, but he did not record it.

It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) concerning this saying of Allah, the Mighty and Majestic: "If you have believed in Allah and in what We sent down to Our servant on the Day of Criterion (al-Furqan)" [Surah al-Anfal: 41] , that he said: By "al-Furqan" is meant the day of the Battle of Badr, the day on which Allah Almighty distinguished between truth and falsehood. This hadith has an authentic (sahih) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it.
