Abu Huraira (Allah be pleased with him) reported: A man came to Messenger of Allah ﷺ and said: I have contracted marriage with a woman of the Ansar, whereupon Allah's Apostle ﷺ said: Did you cast a glance at her, for there is something in the eyes of the Ansar? He said: I did cast a glance at her, whereupon he said: For what (dower) did you marry her? He said: For four 'uqiyas. Thereupon Allah's Apostle ﷺ said: For four 'uqiyas;
it seems as if you dig out silver from the side of this mountain (and that is why you are prepared to pay such a large amount of dower). We have nothing which we should give you. There is a possibility that we may send you to an (expedition) where you may get (booty). So he sent that man (in the expedition) which was despatched to Banu 'Abs.

وَحَدَّثَنِي يَحْيَى بْنُ مَعِينٍ، حَدَّثَنَا مَرْوَانُ بْنُ مُعَاوِيَةَ الْفَزَارِيُّ، حَدَّثَنَا يَزِيدُ بْنُ كَيْسَانَ، عَنْ أَبِي حَازِمٍ، عَنْ أَبِي هُرَيْرَةَ، قَالَ جَاءَ رَجُلٌ إِلَى النَّبِيِّ ﷺ فَقَالَ إِنِّي تَزَوَّجْتُ امْرَأَةً مِنَ الأَنْصَارِ . فَقَالَ لَهُ النَّبِيُّ ﷺ " هَلْ نَظَرْتَ إِلَيْهَا فَإِنَّ فِي عُيُونِ الأَنْصَارِ شَيْئًا " . قَالَ قَدْ نَظَرْتُ إِلَيْهَا . قَالَ " عَلَى كَمْ تَزَوَّجْتَهَا " . قَالَ عَلَى أَرْبَعِ أَوَاقٍ . فَقَالَ لَهُ النَّبِيُّ ﷺ " عَلَى أَرْبَعِ أَوَاقٍ كَأَنَّمَا تَنْحِتُونَ الْفِضَّةَ مِنْ عُرْضِ هَذَا الْجَبَلِ مَا عِنْدَنَا مَا نُعْطِيكَ وَلَكِنْ عَسَى أَنْ نَبْعَثَكَ فِي بَعْثٍ تُصِيبُ مِنْهُ " . قَالَ فَبَعَثَ بَعْثًا إِلَى بَنِي عَبْسٍ بَعَثَ ذَلِكَ الرَّجُلَ فِيهِمْ .
