[Machine] About the Prophet ﷺ who said, "A man should not propose marriage to his brother's fiancée."  

عَنِ النَّبِيِّ ﷺ أَنَّهُ «نَهَى عَنْ أَنْ يَخْطُبَ الرَّجُلُ عَلَى خِطْبَةِ أَخِيهِ»  

The Prophet ﷺ said: One of you must not ask a woman in marriage when his brother has done so already, and one of you must not sell (his own goods) when his brother has already sold (his goods) except with his permission. (Using translation from Abū Dāʾūd 2081)   

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ «لَا يَخْطُبُ أَحَدُكُمْ عَلَى خِطْبَةِ أَخِيهِ وَلَا يَبِيعُ عَلَى بَيْعِ أَخِيهِ حَتَّى يَأْذَنَ لَهُ»  

[Machine] She was under the authority of a man from the Quraysh tribe of Banu Makhzum, but he divorced her abruptly. She then sent a message to her family seeking financial support, but they informed her that they had no provision for her. The Messenger of Allah ﷺ was informed of this, and he said, "You have no financial support, but you have an 'iddah (waiting period). Move to the house of Umm Sharik and do not burden us with your presence." Then he said, "Umm Sharik is a woman who is visited by her brothers from the Muhajirin, but move to the house of Ibn Umm Maktum, for he is a blind man. If you take off your clothes, he will not see anything, and do not burden us with your presence." So she went to the house of Ibn Umm Maktum, and when she arrived, she remembered that Mu'awiyah and Abu Jahm had proposed to her. The Messenger of Allah ﷺ said, "As for Mu'awiyah, he is a man without wealth, and as for Abu Jahm, he does not take his cane off his shoulder. So where do you stand with regard to Usamah?" Her family seemed to dislike this, so she said, "By Allah, I will not marry anyone except the one whom the Messenger of Allah ﷺ has mentioned." Therefore, she married Usamah. Muhammad ibn Amr said that Muhammad ibn Ibrahim said, "O Fatimah, fear Allah, for you have known what this meant."  

أَنَّهَا كَانَتْ تَحْتَ رَجُلٍ مِنْ قُرَيْشٍ مِنْ بَنِي مَخْزُومٍ فَطَلَّقَهَا الْبَتَّةَ فَأَرْسَلَتْ إِلَى أَهْلِهِ تَبْتَغِي مِنْهُمُ النَّفَقَةَ فَقَالُوا لَيْسَ لَكِ نَفَقَةٌ فَبَلَغَ ذَلِكَ رَسُولَ اللَّهِ ﷺ فَقَالَ «لَيْسَ لَكِ نَفَقَةٌ وَعَلَيْكِ الْعِدَّةُ وَانْتَقِلِي إِلَى بَيْتِ أُمِّ شَرِيكٍ وَلَا تُفَوِّتِينَا بِنَفْسِكِ» ثُمَّ قَالَ «إِنَّ أُمَّ شَرِيكٍ امْرَأَةٌ يَدْخُلُ عَلَيْهَا إِخْوَانُهَا مِنَ الْمُهَاجِرِينَ وَلَكِنِ انْتَقِلِي إِلَى بَيْتِ ابْنِ أُمِّ مَكْتُومٍ فَإِنَّهُ رَجُلٌ أَعْمَى إِنْ وَضَعْتِ ثِيَابَكِ لَمْ يَرَ شَيْئًا وَلَا تُفَوِّتِينَا بِنَفْسِكِ» فَانْطَلَقَتْ إِلَى بَيْتِ ابْنِ أُمِّ مَكْتُومٍ فَلَمَّا حَلَّتْ ذَكَرَتْ أَنَّ مُعَاوِيَةَ وَأَبَا جَهْمٍ خَطَبَاهَا فَقَالَ رَسُولُ اللَّهِ ﷺ «أَمَّا مُعَاوِيَةُ فَرَجُلٌ لَا مَالَ لَهُ وَأَمَّا أَبُو جَهْمٍ فَلَا يَضَعُ عَصَاهُ عَنْ عَاتِقِهِ فَأَيْنَ أَنْتَ مِنْ أُسَامَةَ؟» فَكَأَنَّ أَهْلَهَا كَرِهُوا ذَلِكَ فَقَالَتْ وَاللَّهِ لَا أَنْكِحُ إِلَّا الَّذِي قَالَ رَسُولُ اللَّهِ ﷺ فَنَكَحَتْ أُسَامَةَ قَالَ مُحَمَّدُ بْنُ عَمْرٍو قَالَ مُحَمَّدُ بْنُ إِبْرَاهِيمَ يَا فَاطِمَةُ اتَّقِي اللَّهَ فَقَدْ عَلِمْتِ فِي أَيِّ شَيْءٍ كَانَ هَذَا
