وَعَنْ أَنَسٍ: أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ بَاعَ حِلْسًا وَقَدَحًا فَقَالَ: «مَنْ يَشْتَرِي هَذَا الحلس والقدح؟» فَقَالَ رجل: آخذهما بِدِرْهَمٍ. فَقَالَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «مَنْ يَزِيدُ عَلَى دِرْهَمٍ؟» فَأَعْطَاهُ رَجُلٌ دِرْهَمَيْنِ فَبَاعَهُمَا مِنْهُ. رَوَاهُ التِّرْمِذِيُّ وَأَبُو دَاوُدَ وَابْنُ مَاجَهْ

Anas said that God’s Messenger offered for sale a saddle-cloth (woolen cloth placed on a camel under the pack-saddle), and a drinking-vessel, saying, “Who will buy this saddle-cloth and drinking- vessel?” A man offered to take them for a dirham and the Prophet asked whether anyone would give more. A man offered him two dirhams and he sold them to him. Tirmidhi, Abu Dawud and Ibn Majah transmitted it.
