A man among Banu Fazarah got married for a pair of sandals, and the Prophet permitted his marriage.  

أَنَّ رَجُلاً مِنْ بَنِي فَزَارَةَ تَزَوَّجَ عَلَى نَعْلَيْنِ فَأَجَازَ النَّبِيُّ ﷺ نِكَاحَهُ  

A man among Banu Fazarah got married for a pair of sandals, and the Prophet permitted his marriage. (Using translation from Ibn Mājah 1888)  

أَنَّ رَجُلًا مِنْ بَنِي فَزَارَةَ تَزَوَّجَ امْرَأَةً عَلَى نَعْلَيْنِ فَأَجَازَ النَّبِيُّ ﷺ نِكَاحَهُ  

[Machine] A man from the Banu Fazara came to the Prophet ﷺ and said, "I have married a woman on the condition that she wears two sandals." The Prophet ﷺ approved of that, meaning he approved of their marriage.  

جَاءَ رَجُلٌ مِنْ بَنِي فَزَارَةَ إِلَى النَّبِيِّ ﷺ قَالَ إِنِّي تَزَوَّجْتُ امْرَأَةً عَلَى نَعْلَيْنِ فَأَجَازَ النَّبِيُّ ﷺ ذَلِكَ أَيْ نِكَاحَهُ
