باب مَا يُنْهَى عَنْ إِضَاعَةِ الْمَالِ

And the Statement of Allah: "... And Allah likes not mischief..." (V.2:205). "... Verily Allah does not set right the work of Al-Mufsidun (the evil-doers, corrupters)..." (V.10:81) And the Statement of Allah: "Does your Salat (prayer) command that we give up what our fathers used to worship, or that we give up doing what we like with our property?..." (V.11:87) Allah also said: "And give not unto the foolish your property..." (V.4:5) And to keep away from all these (things), and (also) what is forbidden as regards deceit.
وَقَوْلِ اللَّهِ تَعَالَى: {وَاللَّهُ لاَ يُحِبُّ الْفَسَادَ} وَ{لاَ يُصْلِحُ عَمَلَ الْمُفْسِدِينَ}. وَقَالَ فِي قَوْلِهِ: {أَصَلَوَاتُكَ تَأْمُرُكَ أَنْ نَتْرُكَ مَا يَعْبُدُ آبَاؤُنَا أَوْ أَنْ نَفْعَلَ فِي أَمْوَالِنَا مَا نَشَاءُ}. وَقَالَ: {وَلاَ تُؤْتُوا السُّفَهَاءَ أَمْوَالَكُمْ} وَالْحَجْرِ فِي ذَلِكَ، وَمَا يُنْهَى عَنِ الْخِدَاعِ.
Sahih al-Bukhari 2407
حَدَّثَنَا أَبُو نُعَيْمٍ، حَدَّثَنَا سُفْيَانُ، عَنْ عَبْدِ اللَّهِ بْنِ دِينَارٍ، سَمِعْتُ ابْنَ عُمَرَ ـ رضى الله عنهما ـ قَالَ قَالَ رَجُلٌ لِلنَّبِيِّ صلى الله عليه وسلم إِنِّي أُخْدَعُ فِي الْبُيُوعِ‏.‏ فَقَالَ ‏ ‏‏.‏ فَكَانَ الرَّجُلُ يَقُولُهُ‏.‏
"‏ إِذَا بَايَعْتَ فَقُلْ لاَ خِلاَبَةَ ‏"
Ibn `Umar:

A man came to the Prophet (ﷺ) and said, "I am often betrayed in bargaining." The Prophet (ﷺ) advised him, "When you buy something, say (to the seller), 'No deception." The man used to say so afterwards.
