"There is no fast for the one who did not make it incumbent upon himself from the night before."  

ابن ماجة:١٧٠٠ – حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ حَدَّثَنَا خَالِدُ بْنُ مَخْلَدٍ الْقَطَوَانِيُّ عَنْ إِسْحَاقَ بْنِ حَازِمٍ عَنْ عَبْدِ اللَّهِ بْنِ أَبِي بَكْرِ بْنِ عَمْرِو بْنِ حَزْمٍ عَنْ سَالِمٍ عَنِ ابْنِ عُمَرَ عَنْ حَفْصَةَ قَالَتْ

قَالَ رَسُولُ اللَّهِ ﷺ لاَ صِيَامَ لِمَنْ لَمْ يَفْرِضْهُ مِنَ اللَّيْلِ
