the Prophet said: "Whoever does not leave false speech, and acting according to it, then Allah is not in any need of him leaving his food and his drink."  

أَنَّ النَّبِيَّ ﷺ قَالَ مَنْ لَمْ يَدَعْ قَوْلَ الزُّورِ وَالْعَمَلَ بِهِ فَلَيْسَ لِلَّهِ حَاجَةٌ بِأَنْ يَدَعَ طَعَامَهُ وَشَرَابَهُ قَالَ وَفِي الْبَابِ عَنْ أَنَسٍ
