Qurʾān Bukhārī Muslim Nasāʾī Abū Dāwūd Tirmidhī Ibn Mājah Mālik Aḥmad Dārimī Ḥākim Ibn Ḥibbān Ṭabarānī Nasāʾī's Kubrá Bayhaqī al-Luʾluʾ wa-al-Marjān Ibn Rajab's Fifty Riyāḍ al-Ṣāliḥīn Aḥmad's Zuhd Suyūṭī
quran:12:20 –

And they sold him for a reduced price - a few dirhams - and they were, concerning him, of those content with little.  

Then they sold him — they ˹the caravan˺ purchased him from them — for a very low, a diminished, price, a handful of dirhams, 20 or 22; for they, that is, his brothers, set small store by him. So the caravan brought him to Egypt, where the one who had bought him sold him for 20 dinars, two pairs of sandals and two robes.
القرآن:١٢:٢٠ –

وَشَرَوْهُ بِثَمَنٍ بَخْسٍ دَرَاهِمَ مَعْدُودَةٍ وَكَانُوا فِيهِ مِنَ الزَّاهِدِينَ  

{وشروه} باعوه منهم {بثمن بخس} ناقص {دراهم معدودة} عشرين أو اثنين وعشرين {وكانوا} أي إخوته {فيه من الزاهدين} فجاءت به السيارة إلى مصر فباعه الذي اشتراه بعشرين دينارا وزوجي نعل وثوبين.

البيهقي:١٢١٣٥ – أَخْبَرَنَا أَبُو نَصْرٍ عُمَرُ بْنُ عَبْدِ الْعَزِيزِ بْنِ قَتَادَةَ أنبأ أَبُو الْحَسَنِ مُحَمَّدُ بْنُ الْحُسَيْنِ بْنِ إِسْمَاعِيلَ السَّرَّاجُ ثنا أَبُو خَلِيفَةَ ثنا أَبُو الْوَلِيدِ وَابْنُ كَثِيرٍ عَنْ شُعْبَةَ عَنْ يُونُسَ عَنِ الْحَسَنِ عَنْ عَلِيٍّ ؓ أَنَّهُ قَضَى فِي اللَّقِيطِ

أَنَّهُ حُرٌّ وَقَرَأَ هَذِهِ الْآيَةَ {وَشَرَوْهُ بِثَمَنٍ بَخْسٍ دَرَاهِمَ مَعْدُودَةٍ وَكَانُوا فِيهِ مِنَ الزَّاهِدِينَ} [يوسف 20]
