Is wasting money and food haram?

Haram Money & business Quran · 3

Short answer

Yes. Allah forbids extravagance (7:31), and calls wasteful people the brothers of the devils (17:26-27). Spending is encouraged within need and means, and wasting food or money on what has no benefit is sinful.

Quran

۞ يَٰبَنِىٓ ءَادَمَ خُذُوا۟ زِينَتَكُمْ عِندَ كُلِّ مَسْجِدٍۢ وَكُلُوا۟ وَٱشْرَبُوا۟ وَلَا تُسْرِفُوٓا۟ ۚ إِنَّهُۥ لَا يُحِبُّ ٱلْمُسْرِفِينَ ﴿٣١﴾

O Children of Adam! Look to your adornment at every place of worship, and eat and drink, but be not prodigal. Lo! He loveth not the prodigals.

وَءَاتِ ذَا ٱلْقُرْبَىٰ حَقَّهُۥ وَٱلْمِسْكِينَ وَٱبْنَ ٱلسَّبِيلِ وَلَا تُبَذِّرْ تَبْذِيرًا ﴿٢٦﴾

Give the kinsman his due, and the needy, and the wayfarer, and squander not (thy wealth) in wantonness.

إِنَّ ٱلْمُبَذِّرِينَ كَانُوٓا۟ إِخْوَٰنَ ٱلشَّيَٰطِينِ ۖ وَكَانَ ٱلشَّيْطَٰنُ لِرَبِّهِۦ كَفُورًۭا ﴿٢٧﴾

Lo! the squanderers were ever brothers of the devils, and the devil was ever an ingrate to his Lord.
