Wasting money

Narrated 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.

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 ‏

‏ إِذَا بَايَعْتَ فَقُلْ لاَ خِلاَبَةَ ‏

‏‏.‏ فَكَانَ الرَّجُلُ يَقُولُهُ‏.‏

Narrated Al-Mughira bin Shu`ba:

The Prophet (ﷺ) said, "Allah has forbidden for you, (1) to be undutiful to your mothers, (2) to bury your daughters alive, (3) to not to pay the rights of the others (e.g. charity, etc.) and (4) to beg of men (begging). And Allah has hated for you (1) vain, useless talk, or that you talk too much about others, (2) to ask too many questions, (in disputed religious matters) and (3) to waste the wealth (by extravagance).

حَدَّثَنَا عُثْمَانُ، حَدَّثَنَا جَرِيرٌ، عَنْ مَنْصُورٍ، عَنِ الشَّعْبِيِّ، عَنْ وَرَّادٍ، مَوْلَى الْمُغِيرَةِ بْنِ شُعْبَةَ عَنِ الْمُغِيرَةِ بْنِ شُعْبَةَ، قَالَ قَالَ النَّبِيُّ صلى الله عليه وسلم ‏

‏ إِنَّ اللَّهَ حَرَّمَ عَلَيْكُمْ عُقُوقَ الأُمَّهَاتِ، وَوَأْدَ الْبَنَاتِ، وَمَنَعَ وَهَاتِ، وَكَرِهَ لَكُمْ قِيلَ وَقَالَ، وَكَثْرَةَ السُّؤَالِ، وَإِضَاعَةَ الْمَالِ ‏
