Ka’b ibn Mālik, may Allāh be pleased with him, said: Whoever fasts the month of Ramadān and he says to himself that he will return to sinful disobedience when Ramadān is over, his fasting is rejected.

عن ابن رجب رحمه الله قَالَ كَعْبْ بْنُ مَالِكٍ رَضِيَ الله عَنْهُ ‏مَنْ صَامَ رَمَضَـانَ وَهُوَ يُحَدِّثُ نَفْسَـهُ أَنَّهُ إِذَا خَرَجَ رَمَضَـانُ عَصَىٰ رَبَّهُ فَصِيَامُهُ عَلَيْهِ مَـرْدُوْدٌ
