وَمَا كَانَ لِنَبِىٍّ أَن يَغُلَّ ۚ وَمَن يَغْلُلْ يَأْتِ بِمَا غَلَّ يَوْمَ ٱلْقِيَٰمَةِ ۚ ثُمَّ تُوَفَّىٰ كُلُّ نَفْسٍۢ مَّا كَسَبَتْ وَهُمْ لَا يُظْلَمُونَ
It is not for any prophet to embezzle. Whoso embezzleth will bring what he embezzled with him on the Day of Resurrection. Then every soul will be paid in full what it hath earned; and they will not be wronged.
Surah Aal-i-Imraan(3:161)
