1403. hadíth
قَالَ رَسُولُ اَللَّهِ صَلَّى اَللَّهُ عَلَيْهِ وَ آلِهِ، لِزَيْنَبَ اَلْعَطَّارَةِ اَلْحَوْلاَءِ "إِذَا بِعْتِ فَأَحْسِنِي وَ لاَ تَغُشِّي فَإِنَّهُ أَنْقَى وَ أَبْقَى لِلْمَالِ ".
The Messenger of Allah (swt) (may Allah (swt) bless him and his family) said to Zaynab, the perfume seller, known as Al-Hawla': "When you sell, do so with excellence and do not deceive, for it is purer and more enduring for wealth."
