His father wrote to Umar bin Abdullah bin Arqam Zuhri instructing him to visit Subayah bint Harith Aslamiyyah and ask her about her case and what the Messenger of Allah ﷺ had told her when she sought his ruling. So Umar bin Abdullah wrote to Abdullah bin Utbah informing him that Subayah had told him the following.She had been married to Saad bin Khawla, who was from the tribe of Amir bin Luayy and one of those who fought at Badr. He died during the Farewell Pilgrimage while she was pregnant. Not long after his death, she gave birth. Once she had recovered from her postnatal bleeding, she adorned herself for suitors.Abu Sanabil bin Bakak, a man from the tribe of Banu Abd al-Dar, came to her and said, "Why do I see you all dressed up? Perhaps you are hoping to remarry. By Allah, you cannot marry until four months and ten days have passed."Subayah said, "When he said that to me, I gathered my clothes around me that evening and went to the Messenger of Allah ﷺ to ask him about it. He gave me the ruling that I had become lawful to remarry the moment I gave birth, and he told me to marry if I wished."Ibn Shihab said, "I see no harm in her marrying as soon as she gives birth, even if she is still bleeding, except that her husband should not approach her until she becomes pure."
أن أباه كتب إلى عمر بن عبد الله بن الأرقم الزهري، يأمره أن يدخل على سبيعة بنت الحارث الأسلمية، فيسألها عن حديثها وعما قال لها رسول الله ﷺ. حين استفته. فكتب عمر بن عبد الله إلى عبد الله بن عتبة يخبره، أن سبيعة أخبرته، أنها كانت تحت سعد بن خولة. وهو في بني عامر بن لؤي. وكان ممن شهد بدرا. فتوفي عنها في حجة الوداع وهي حامل. فلم تنشب أن وضعت حملها بعد وفاته. فلما تعلت من نفاسها تجملت للخطاب. فدخل عليها أبو السنابل بن بعكك (رجل من بني عبد الدار) فقال لها: ما لي أراك متجملة؟ لعلك ترجين النكاح. إنك، والله! ما أنت بناكح حتى تمر عليك أربعة أشهر وعشر. قالت سبيعة: فلما قال لي ذلك، جمعت علي ثيابي حين أمسيت. فأتيت رسول الله ﷺ فسألته عن ذلك؟ فأفتاني بأني قد حللت حين وضعت حملي. وأمرني بالتزوج إن بدا لي. قال ابن شهاب: فلا أرى بأسا أن تتزوج حين وضعت. وإن كانت دمها. غير أن لا يقربها زوجها حتى تطهر.
Bukhari narrated it in Talaq (5319) through the route of Yazid, and Muslim narrated it in Talaq (1484) through the route of Yunus bin Yazid, both of them from Ibn Shihab Zuhri, who said, Ubaydullah bin Abdullah bin Utba bin Masud narrated to me that his father wrote to Umar bin Abdullah bin Arqam Zuhri, and he mentioned it, the wording being Muslim's, while Bukhari's version is very abridged.He cited it without a connected chain in Maghazi (3991) from Layth, who said, Yunus narrated to me, from Ibn Shihab, with the same chain, and he mentioned it in full.Al-Hafiz said in Fath al-Bari (311/7), "He connected it in Tarikh al-Kabir, where he said, Abdullah bin Salih said to us, Layth informed us," and he mentioned it in full.
