Sunan at-Tirmithiy كتاب الصوم باب ما جاء فى التشديد فى الغيبة للصائم
حَدَّثَنَا أَبُو مُوسَى مُحَمَّدُ بْنُ الْمُثَنَّى حَدَّثَنَا عُثْمَانُ بْنُ عُمَرَ أَخْبَرَنَا ابْنُ أَبِى ذِئْبٍ عَنْ سَعِيدٍ الْمَقْبُرِىِّ عَنْ أَبِيهِ عَنْ أَبِى هُرَيْرَةَ أَنَّ النَّبِىَّ صلى الله عليه وسلم قَالَ مَنْ لَمْ يَدَعْ قَوْلَ الزُّورِ وَالْعَمَلَ بِهِ فَلَيْسَ لِلَّهِ حَاجَةٌ بِأَنْ يَدَعَ طَعَامَهُ وَشَرَابَهُ. قَالَ وَفِى الْبَابِ عَنْ أَنَسٍ. قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ.
The Prophet, peace and blessings of God be upon him, said, "Whoever does not abstain from falsehood in speech (1) and action (2) [while fasting], then God is in no need that he abstains from food and drink (3)."
(1) This includes lying, false accusation, cursing, swearing, and similar forms of speech. (2) All evil deeds. (3) God, Almighty and Sublime is He, does not need anything from anyone. This hadīth indicates that the purpose of fasting is to restrain and improve one's self, failiure to do so, makes the fasting meaningless.
