quran:47:37 –

If He should ask you for them and press you, you would withhold, and He would expose your unwillingness.  

If He were to ask you for it, and press you, demand it persistently, you would be niggardly, and this, niggardliness, would expose your rancour, towards the religion of Islam.
القرآن:٤٧:٣٧ –

إِنْ يَسْأَلْكُمُوهَا فَيُحْفِكُمْ تَبْخَلُوا وَيُخْرِجْ أَضْغَانَكُمْ  

{إن يسألكموها فحيفكم} يبالغ في طلبها {تبخلوا ويخرج} البخل {أضغانكم} لدين الإسلام.
