وَٱلَّذِينَ إِذَآ أَنفَقُواْ لَمۡ يُسۡرِفُواْ وَلَمۡ يَقۡتُرُواْ وَكَانَ بَيۡنَ ذَٰلِكَ قَوَامٗا ٦٧
And [they are] those who, when they spend, do so not excessively or sparingly but are ever, between that, [justly] moderate
Translation: Saheeh International (English)
Each word's meaning and sound
They are those whom when they spend their wealth do not go to the limit of extravagance in their spending, nor do they restrict their spending to only those whom they have to spend on such as themselves and others, but their spending is balanced between wastefulness and niggardliness.
