قَوْلُهُ تَعَالَى: {وَامْرَأَةً مُؤْمِنَةً إِنْ وَهَبَتْ نَفْسَهَا لِلنَّبِيِّ} [الأحزاب: 50]
It was narrated that Sahl bin Sa'd said: "I was among the people when a woman said: 'I offer myself (in marriage) to you, O Messenger of Allah, see what you think of me.' A man stood up and said: 'Marry me to her.' He said: 'Go and find (something), even if it is an iron ring.' So he went, but he could not find anything, not even an iron ring. So the Messenger of Allah said: 'Do you have (memorized) any surahs of the Qur'an?' He said: 'Yes.' So he married him to her on the basis of what he knew of surahs of the Qur'an." (Using translation from Nasāʾī 3200)
قَالَتِ امْرَأَةٌ إِنِّي قَدْ وَهَبْتُ لَكَ نَفْسِي يَا رَسُولَ اللهِ فَرَّ فِيَّ رَأْيَكَ يَا رَسُولَ اللهِ فَقَامَ رَجُلٌ فَقَالَ زَوِّجْنِيهَا قَالَ «اذْهَبْ فَاطْلُبْ وَلَوْ خَاتَمًا مِنْ حَدِيدٍ» فَذَهَبَ وَلَمْ يَجِئْ بِشَيْءٍ وَلَا بِخَاتَمٍ مِنْ حَدِيدٍ فَقَالَ رَسُولُ اللهِ ﷺ «مَعَكَ مِنْ سُوَرِ الْقُرْآنِ شَيْءٌ؟» قَالَ نَعَمْ قَالَ فَزَوَّجَهُ بِمَا مَعَهُ مِنْ سُوَرِ الْقُرْآنِ
