Allah Almighty describes the squanderers as “brothers of the devils”.
The best course is the middle course. A person should neither be too miserly nor too extravagant.
Squandering is the act of spending money in wrong ways such as spending it in illegal ways.
(Give to close relatives their due, as well as the poor and ˹needy˺ travellers. And do not spend wastefully. Surely the wasteful are ˹like˺ brothers to the devils. And the Devil is ever ungrateful to his Lord.) Al-Israa 17:26-27
التبذير هو إنفاق المال في غير وجهه الصحيح كإنفاقه في الحرام.
(وَآتِ ذَا الْقُرْبَىٰ حَقَّهُ وَالْمِسْكِينَ وَابْنَ السَّبِيلِ وَلَا تُبَذِّرْ تَبْذِيرًا ﴿٢٦﴾ إِنَّ الْمُبَذِّرِينَ كَانُوا إِخْوَانَ الشَّيَاطِينِ ۖ وَكَانَ الشَّيْطَانُ لِرَبِّهِ كَفُورًا) الإسراء 17: 26-27
