ذِكْرُ الْإِبَاحَةِ لِلْمَرْءِ أَنْ يَكُونَ وَزَّانًا لِلنَّاسِ بَعْدَ أَنْ يَلْزَمَ النَّصِيحَةَ فِي أُمُورِهِ وَأَسْبَابِهِ
"Makhrafah Al' Abdi and I brought linens from Hajar[1] The Messenger of Allah ﷺ came to us to bargain with us with some trousers. There was someone with me who weighed (the goods) in exchange for a wage. So the Prophet ﷺ said to the one weighing: 'Weigh and add more.'" (Using translation from Ibn Mājah 2220)
جَلَبْتُ أَنَا وَمَخْرَفَةُ الْعَبْدِيُّ بَزًّا مِنْ هَجَرَ فَأَتَانَا رَسُولُ اللَّهِ ﷺ فَسَاوَمَنَا سَرَاوِيلَ وَعِنْدَهُ وَزَّانٌ يَزِنُ بِالْأَجْرِ فَقَالَ لَهُ النَّبِيُّ ﷺ «زِنْ فَأَرْجِحْ» أَرَادَ بِهِ مِنْ مَالِهِ لِيُعْطِيَ ثَمَنَ السَّرَاوِيلِ رَاجِحًا
