"The Messenger of Allah ﷺ said: 'Allah does not accept Salah without purification, nor charity from Ghulul.'" [1] [1] That which is taken from the spoils of war prior to their distribution. (Using translation from Nasāʾī 139)
"إِنَّ الله لَا يَقْبَلُ صَلَاةً بِغَيرِ طَهُور وَلَا صَدَقَةً مِنْ غُلُولٍ".
