Malik related to me from Ibn Shihab that he had heard that in the time of the Messenger of Allah ﷺ women were becoming muslim in their own lands and they did not do hijra while their husbands were still kafirun although they themselves had become muslim. Among them was the daughter of al-Walid ibn al-Mughira and she was the wife of Safwan ibn Umayya. She became muslim on the day of the conquest (of Makka), and her husband, Safwan ibn Umayya fled from Islam. The Messenger of Allah ﷺ sent Safwan's paternal cousin, Wahb ibn Umayr with the cloak of the Messenger of Allah ﷺ as a safe-conduct for Safwan ibn Umayya, and the Messenger of Allah ﷺ called him to Islam and asked for him to come to him and if he was pleased with the matter to accept it. If not he would have a respite for two months.
When Safwan came to the Messenger of Allah ﷺ with his cloak, he called out to him over the heads of the people, "Muhammad! Wahb ibn Umayr brought me your cloak and claimed that you had summoned me to come to you and if I was pleased with the matter, I should accept it and if not, you would give me a respite for two months. "The Messenger of Allah ﷺ said, "Come down, Abu Wahb." He said, "No, by Allah! I will not come down until you make it clear to me." The Messenger of Allah ﷺ said, "You have a respite of four months." The Messenger of Allah ﷺ went out toward Hawazin at Hunayn. He sent to Safwan ibn Umayya to borrow some equipment and arms that he had. Safwan said, "Willingly or unwillingly?" He said, "Willingly." Therefore he lent him the equipment and arms which he had. Then Safwan went out with the Messenger of Allah ﷺ while he was still a kafir. He was present at the battles of Hunayn and at-Ta'if while he was still a kafir and his wife was a muslim. The Messenger of Allah ﷺ did not separate Safwan and his wife until he had become muslim, and his wife was settled with him by that marriage.

حَدَّثَنِي مَالِكٌ، عَنِ ابْنِ شِهَابٍ، أَنَّهُ بَلَغَهُ أَنَّ نِسَاءً، كُنَّ فِي عَهْدِ رَسُولِ اللَّهِ ﷺ يُسْلِمْنَ بِأَرْضِهِنَّ وَهُنَّ غَيْرُ مُهَاجِرَاتٍ وَأَزْوَاجُهُنَّ حِينَ أَسْلَمْنَ كُفَّارٌ مِنْهُنَّ بِنْتُ الْوَلِيدِ بْنِ الْمُغِيرَةِ . وَكَانَتْ تَحْتَ صَفْوَانَ بْنِ أُمَيَّةَ فَأَسْلَمَتْ يَوْمَ الْفَتْحِ وَهَرَبَ زَوْجُهَا صَفْوَانُ بْنُ أُمَيَّةَ مِنَ الإِسْلاَمِ فَبَعَثَ إِلَيْهِ رَسُولُ اللَّهِ ﷺ ابْنَ عَمِّهِ وَهْبَ بْنَ عُمَيْرٍ بِرِدَاءِ رَسُولِ اللَّهِ ﷺ أَمَانًا لِصَفْوَانَ بْنِ أُمَيَّةَ وَدَعَاهُ رَسُولُ اللَّهِ ﷺ إِلَى الإِسْلاَمِ وَأَنْ يَقْدَمَ عَلَيْهِ فَإِنْ رَضِيَ أَمْرًا قَبِلَهُ وَإِلاَّ سَيَّرَهُ شَهْرَيْنِ فَلَمَّا قَدِمَ صَفْوَانُ عَلَى رَسُولِ اللَّهِ ﷺ بِرِدَائِهِ نَادَاهُ عَلَى رُءُوسِ النَّاسِ فَقَالَ يَا مُحَمَّدُ إِنَّ هَذَا وَهْبَ بْنَ عُمَيْرٍ جَاءَنِي بِرِدَائِكَ وَزَعَمَ أَنَّكَ دَعَوْتَنِي إِلَى الْقُدُومِ عَلَيْكَ فَإِنْ رَضِيتُ أَمْرًا قَبِلْتُهُ وَإِلاَّ سَيَّرْتَنِي شَهْرَيْنِ . فَقَالَ رَسُولُ اللَّهِ ﷺ " انْزِلْ أَبَا وَهْبٍ " . فَقَالَ لاَ وَاللَّهِ لاَ أَنْزِلُ حَتَّى تُبَيِّنَ لِي . فَقَالَ رَسُولُ اللَّهِ ﷺ " بَلْ لَكَ تَسِيرُ أَرْبَعَةَ أَشْهُرٍ " . فَخَرَجَ رَسُولُ اللَّهِ ﷺ قِبَلَ هَوَازِنَ بِحُنَيْنٍ . فَأَرْسَلَ إِلَى صَفْوَانَ بْنِ أُمَيَّةَ يَسْتَعِيرُهُ أَدَاةً وَسِلاَحًا عِنْدَهُ فَقَالَ صَفْوَانُ أَطَوْعًا أَمْ كَرْهًا فَقَالَ " بَلْ طَوْعًا " . فَأَعَارَهُ الأَدَاةَ وَالسِّلاَحَ الَّتِي عِنْدَهُ ثُمَّ خَرَجَ صَفْوَانُ مَعَ رَسُولِ اللَّهِ ﷺ وَهُوَ كَافِرٌ فَشَهِدَ حُنَيْنًا وَالطَّائِفَ وَهُوَ كَافِرٌ وَامْرَأَتُهُ مُسْلِمَةٌ وَلَمْ يُفَرِّقْ رَسُولُ اللَّهِ ﷺ بَيْنَهُ وَبَيْنَ امْرَأَتِهِ حَتَّى أَسْلَمَ صَفْوَانُ وَاسْتَقَرَّتْ عِنْدَهُ امْرَأَتُهُ بِذَلِكَ النِّكَاحِ .
