Narrated Sahl bin Sad As-Sa'idi:

A woman came to Allah's Apostle and said, "O Allah's Apostle! I have come to give you myself in marriage (without Mahr)." Allah's Apostle looked at her. He looked at her carefully and fixed his glance on her and then lowered his head. When the lady saw that he did not say anything, she sat down. A man from his companions got up and said, "O Allah's Apostle! If you are not in need of her, then marry her to me." The Prophet ﷺ said, "Have you got anything to offer?" The man said, "No, by Allah, O Allah's Apostle!" The Prophet ﷺ said (to him), "Go to your family and see if you have something." The man went and returned, saying, "No, by Allah, I have not found anything." Allah's Apostle ﷺ said, "(Go again) and look for something, even if it is an iron ring." He went again and returned, saying, "No, by Allah, O Allah's Apostle! I could not find even an iron ring, but this is my Izar (waist sheet)." He had no rida. He added, "I give half of it to her." Allah's Apostle ﷺ said, "What will she do with your Izar? If you wear it, she will be naked, and if she wears it, you will be naked." So that man sat down for a long while and then got up (to depart). When Allah's Apostle saw him going, he ordered that he be called back. When he came, the Prophet ﷺ said, "How much of the Quran do you know?" He said, "I know such Sura and such Sura," counting them. The Prophet ﷺ said, "Do you know them by heart?" He replied, "Yes." The Prophet ﷺ said, "Go, I marry her to you for that much of the Quran which you have."

حَدَّثَنَا قُتَيْبَةُ، حَدَّثَنَا عَبْدُ الْعَزِيزِ بْنُ أَبِي حَازِمٍ، عَنْ أَبِيهِ، عَنْ سَهْلِ بْنِ سَعْدٍ السَّاعِدِيِّ، قَالَ جَاءَتِ امْرَأَةٌ إِلَى رَسُولِ اللَّهِ ﷺ فَقَالَتْ يَا رَسُولَ اللَّهِ جِئْتُ أَهَبُ لَكَ نَفْسِي قَالَ فَنَظَرَ إِلَيْهَا رَسُولُ اللَّهِ ﷺ فَصَعَّدَ النَّظَرَ فِيهَا وَصَوَّبَهُ ثُمَّ طَأْطَأَ رَسُولُ اللَّهِ ﷺ رَأْسَهُ فَلَمَّا رَأَتِ الْمَرْأَةُ أَنَّهُ لَمْ يَقْضِ فِيهَا شَيْئًا جَلَسَتْ فَقَامَ رَجُلٌ مِنْ أَصْحَابِهِ فَقَالَ يَا رَسُولَ اللَّهِ إِنْ لَمْ يَكُنْ لَكَ بِهَا حَاجَةٌ فَزَوِّجْنِيهَا. فَقَالَ " وَهَلْ عِنْدَكَ مِنْ شَىْءٍ ". قَالَ لاَ وَاللَّهِ يَا رَسُولَ اللَّهِ. فَقَالَ " اذْهَبْ إِلَى أَهْلِكَ فَانْظُرْ هَلْ تَجِدُ شَيْئًا ". فَذَهَبَ ثُمَّ رَجَعَ فَقَالَ لاَ وَاللَّهِ مَا وَجَدْتُ شَيْئًا. فَقَالَ رَسُولُ اللَّهِ ﷺ " انْظُرْ وَلَوْ خَاتَمًا مِنْ حَدِيدٍ ". فَذَهَبَ ثُمَّ رَجَعَ فَقَالَ لاَ وَاللَّهِ يَا رَسُولَ اللَّهِ وَلاَ خَاتَمًا مِنْ حَدِيدٍ وَلَكِنْ هَذَا إِزَارِي ـ قَالَ سَهْلٌ مَا لَهُ رِدَاءٌ فَلَهَا نِصْفُهُ ـ فَقَالَ رَسُولُ اللَّهِ ﷺ " مَا تَصْنَعُ بِإِزَارِكَ إِنْ لَبِسْتَهُ لَمْ يَكُنْ عَلَيْهَا مِنْهُ شَىْءٌ وَإِنْ لَبِسَتْهُ لَمْ يَكُنْ عَلَيْكَ شَىْءٌ ". فَجَلَسَ الرَّجُلُ حَتَّى إِذَا طَالَ مَجْلِسُهُ قَامَ فَرَآهُ رَسُولُ اللَّهِ ﷺ مُوَلِّيًا فَأَمَرَ بِهِ فَدُعِيَ فَلَمَّا جَاءَ قَالَ " مَاذَا مَعَكَ مِنَ الْقُرْآنِ ". قَالَ مَعِي سُورَةُ كَذَا وَسُورَةُ كَذَا عَدَّدَهَا. فَقَالَ " تَقْرَؤُهُنَّ عَنْ ظَهْرِ قَلْبِكَ ". قَالَ نَعَمْ. قَالَ " اذْهَبْ فَقَدْ مَلَّكْتُكَهَا بِمَا مَعَكَ مِنَ الْقُرْآنِ ".
