It is narrated from Umarah bin Khuzaymah bin Thabit; he said: We were with Sayyiduna Amr bin al-As (may Allah be pleased with him) on a journey for Hajj or Umrah. When we reached Marr al-Zahran, we saw a woman in her howdah (camel litter) with her hand resting on the howdah. Then, when we descended into a mountain pass, we saw many crows there, among which was a piebald crow with a red beak and red legs. So Sayyiduna Amr bin al-As (may Allah be pleased with him) said that the Messenger of Allah (peace and blessings be upon him) said: "None of the women will enter Paradise except the one whose likeness is like this piebald crow among these (black) crows." This hadith is sahih (authentic) on the condition of Imam Muslim, but the two Shaykhs did not record it.
