bayhaqi:13762Abū Zakariyyā b. Abū Isḥāq al-Muzakkī > Abū ʿAbdullāh Muḥammad b. Yaʿqūb > Muḥammad b. ʿAbd al-Wahhāb > Jaʿfar b. ʿAwn > Misʿar > Saʿd b. Ibrāhīm > Ibrāhīm b. Muḥammad b. Ṭalḥah > ʿUmar

[Machine] Umar said, "It is not suitable for those who are responsible for their own affairs to marry except those who are competent." The Sheikh, may Allah have mercy on him, said that Al-Shafi'i, may Allah have mercy on him, made the meaning conditional on the consent of the guardians in marriage so that the woman does not harm herself. He said it has no meaning other than that it is preferable for her to only marry a suitable partner. Rather, I do not think it is possible that a matter is established for them with the woman herself except in order for her to marry only a suitable partner. Abu Sa'id ibn Abi 'Amr informed us, Abu al-Abbas reported to us, and Rabi' reported to us that Al-Shafi'i, may Allah have mercy on him, mentioned it.  

البيهقي:١٣٧٦٢أَخْبَرَنَا أَبُو زَكَرِيَّا بْنُ أَبِي إِسْحَاقَ الْمُزَكِّي أنبأ أَبُو عَبْدِ اللهِ مُحَمَّدُ بْنُ يَعْقُوبَ ثنا مُحَمَّدُ بْنُ عَبْدِ الْوَهَّابِ أنبأ جَعْفَرُ بْنُ عَوْنٍ أنبأ مِسْعَرٌ عَنْ سَعْدِ بْنِ إِبْرَاهِيمَ عَنْ إِبْرَاهِيمَ بْنِ مُحَمَّدِ بْنِ طَلْحَةَ قَالَ

قَالَ عُمَرُ ؓ لَا يَنْبَغِي لِذَوَاتِ الْأَحْسَابِ تَزَوُّجُهُنَّ إِلَّا مِنَ الْأَكْفَاءِ قَالَ الشَّيْخُ رَحِمَهُ اللهُ وَقَدْ جَعَلَ الشَّافِعِيُّ رَحِمَهُ اللهُ الْمَعْنَى فِي اشْتِرَاطِ الْوُلَاةِ فِي النِّكَاحِ كَيْلَا تُضَيِّعَ الْمَرْأَةُ نَفْسَهَا فَقَالَ لَا مَعْنَى لَهُ أَوْلَى بِهِ مِنْ أَنْ لَا تَزَوَّجَ إِلَّا كُفُؤًا بَلْ لَا أَحْسَبُهُ يَحْتَمِلُ أَنْ يَكُونَ جُعِلَ لَهُمْ أَمْرٌ مَعَ الْمَرْأَةِ فِي نَفْسِهَا إِلَّا لِئَلَّا تَنْكِحَ إِلَّا كُفُوًا أَخْبَرَنَا بِذَلِكَ أَبُو سَعِيدِ بْنُ أَبِي عَمْرٍو ثنا أَبُو الْعَبَّاسِ أَنْبَأَ الرَّبِيعُ أَنْبَأَ الشَّافِعِيُّ رَحِمَهُ اللهُ فَذَكَرَهُ
