وَالَّذِينَ إِذَا أَنفَقُوا لَمْ يُسْرِفُوا وَلَمْ يَقْتُرُوا وَكَانَ بَيْنَ ذَٰلِكَ قَوَامًا

A man’s way of walking symbolises his whole personality. Those in whose hearts belief in God has taken firm root, become the embodiment of humility and modesty. The fear of God takes away any sense of superiority they may have. This sense of servitude to God permeates all aspects of their lives. But this is not all. The realisation of God makes them (the believers) true advocates of His cause. In discharging this responsibility, they often face strong opposition from their addressees. The promulgation of the truth by the believers becomes unbearable to those who deny the truth and they take aggressive action against the preachers. But the fear of God prevents the believers from retaliating; they simply avoid conflict and pray for their opponents to be guided. The realization of God results not only in their calling upon God during the daytime but also in their nights being filled with the remembrance of God. Similarly, realisation of God makes them extremely prudent. They earn with a sense of responsibility and spend with a sense of responsibility. It is their sense of accountability to God which makes them moderate and cautious in the matter of income and expenditure. A tradition of the Prophet says, ‘Wisdom lies in man adopting the path of moderation.’
