۞ يَٰبَنِىٓ ءَادَمَ خُذُوا۟ زِينَتَكُمْ عِندَ كُلِّ مَسْجِدٍۢ وَكُلُوا۟ وَٱشْرَبُوا۟ وَلَا تُسْرِفُوٓا۟ ۚ إِنَّهُۥ لَا يُحِبُّ ٱلْمُسْرِفِينَ ﴿٣١﴾
阿丹的子孙啊！-逢礼拜，你们必须穿著服饰。你们应当吃，应当喝，但不要过分，真主确是不喜欢过分者的。

Quran
وَءَاتِ ذَا ٱلْقُرْبَىٰ حَقَّهُۥ وَٱلْمِسْكِينَ وَٱبْنَ ٱلسَّبِيلِ وَلَا تُبَذِّرْ تَبْذِيرًا ﴿٢٦﴾
你应当把亲戚、贫民、旅客所应得的周济分给他们，你不要挥霍；
إِنَّ ٱلْمُبَذِّرِينَ كَانُوٓا۟ إِخْوَٰنَ ٱلشَّيَٰطِينِ ۖ وَكَانَ ٱلشَّيْطَٰنُ لِرَبِّهِۦ كَفُورًۭا ﴿٢٧﴾
挥霍者确是恶魔的朋友，恶魔原是辜负主恩的。
