"I was among the people with the Prophet when a woman stood up and said: 'O Messenger of Allah, she has offered herself in marriage to you, so see what you think of her.' He remained silent and the Prophet did not give any answer. Then she stood up (again) and said: 'O Messenger of Allah, she has offered herself in marriage to you, so see what you think of her.' A man stood up and said: 'Marry her to me, O Messenger of Allah!' He said: 'Do you have anything?' He said: 'No.' He said: 'Go and look, even if it is just an iron ring.' So he went and looked then he came and said: 'I could not find anything, not even an iron ring.' He said: 'Have you memorized anything of the Qur'an?' He said: 'Yes, Surah such-and-such and Surah such-and-such.' He said: 'I will marry you to her on the basis of what you have memorized of the Qur'an.'"  

سَمِعْتُ سَهْلَ بْنَ سَعْدٍ يَقُولُ إِنِّي لَفِي الْقَوْمِ عِنْدَ النَّبِيِّ ﷺ فَقَامَتِ امْرَأَةٌ فَقَالَتْ يَا رَسُولَ اللَّهِ إِنَّهَا قَدْ وَهَبَتْ نَفْسَهَا لَكَ فَرَأْ فِيهَا رَأْيَكَ فَسَكَتَ فَلَمْ يُجِبْهَا النَّبِيُّ ﷺ بِشَىْءٍ ثُمَّ قَامَتْ فَقَالَتْ يَا رَسُولَ اللَّهِ إِنَّهَا قَدْ وَهَبَتْ نَفْسَهَا لَكَ فَرَأْ فِيهَا رَأْيَكَ فَقَامَ رَجُلٌ فَقَالَ زَوِّجْنِيهَا يَا رَسُولَ اللَّهِ قَالَ هَلْ مَعَكَ شَىْءٌ قَالَ لاَ قَالَ اذْهَبْ فَاطْلُبْ وَلَوْ خَاتَمًا مِنْ حَدِيدٍ فَذَهَبَ فَطَلَبَ ثُمَّ جَاءَ فَقَالَ لَمْ أَجِدْ شَيْئًا وَلاَ خَاتَمًا مِنْ حَدِيدٍ قَالَ هَلْ مَعَكَ مِنَ الْقُرْآنِ شَىْءٌ قَالَ نَعَمْ مَعِي سُورَةُ كَذَا وَسُورَةُ كَذَا قَالَ قَدْ أَنْكَحْتُكَهَا عَلَى مَا مَعَكَ مِنَ الْقُرْآنِ  

[Machine] He said: While we were with the Messenger of Allah ﷺ , a woman approached him and said, "O Messenger of Allah, I offer myself to you as a gift." He looked at her up and down and straightened himself. Then he remained silent. A man stood up who had nothing on him except for a single garment tied around his neck. He said, "If you don't need her, then marry her to me." The Prophet ﷺ asked him, "Do you have anything to give as a dowry?" He replied, "No." The Prophet ﷺ said, "Then you must find something. Go and look for it." So he went and searched, but he found nothing. He returned and said, "I couldn't find anything." The Prophet ﷺ told him, "Go and search, even if it's just a ring made of iron." So he went and returned, saying, "I couldn't find even a ring made of iron." Then he sat down, and the Prophet ﷺ asked him, "Do you have any part of the Quran with you?" He replied, "Surah such and such and Surah such and such." The Prophet ﷺ said, "I have married her to you based on what you have of the Quran."  

أَنَّهُ قَالَ بَيْنَمَا نَحْنُ عِنْدَ رَسُولِ اللهِ ﷺ أَقْبَلَتِ امْرَأَةٌ إِلَيْهِ فَقَالَتْ إِنِّي جِئْتُ يَا رَسُولَ اللهِ أَهَبُ لَكَ نَفْسِي فَصَعَّدَ فِيهَا النَّظَرَ وَصَوَّبَهُ ثُمَّ سَكَتَ فَقَامَ رَجُلٌ مَا عَلَيْهِ إِلَّا ثَوْبٌ وَاحِدٌ عَاقِدٌ طَرَفَيْهِ عَلَى عُنُقَهِ فَقَالَ إِنْ لَمْ يَكُنْ لَكَ بِهَا حَاجَةٌ فَزَوِّجْنِيهَا فَقَالَ لَهُ «أَعِنْدَكَ شَيْءٌ؟» قَالَ لَا قَالَ «فَلَا بُدَّ لَهَا مِنْ شَيْءٍ فَاذْهَبْ فَالْتَمِسْ» فَذَهَبَ فَالْتَمَسَ فَلَمْ يَجِدْ شَيْئًا فَرَجَعَ فَقَالَ لَمْ أَجِدْ شَيْئًا فَقَالَ لَهُ رَسُولُ اللهِ ﷺ «اذْهَبْ فَالْتَمِسْ وَلَوْ خَاتَمًا مِنْ حَدِيدٍ» فَذَهَبَ ثُمَّ رَجَعَ فَقَالَ وَلَا خَاتَمًا مِنْ حَدِيدٍ لَمْ أَجِدْهُ ثُمَّ جَلَسَ فَقَالَ لَهُ رَسُولُ اللهِ ﷺ «مَا مَعَكَ مِنَ الْقُرْآنِ؟» فَقَالَ سُورَةُ كَذَا وَسُورَةُ كَذَا فَقَالَ «قَدْ زَوَّجْتُكَهَا عَلَى مَا مَعَكَ مِنَ الْقُرْآنِ»
