Fasting
Voluntary Fasting - Section 1
وَعَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: لَا صَوْم فِي يَوْمَيْنِ: الْفطر وَالضُّحَى
He reported God’s messenger as saying, “No fast is to be observed on two days, al-Fitr and al-Adha.* *In this tradition I have used the Arabic words, but have translated them in the preceding tradition. In the preceding tradition an-nahr is used where al-Adha is used here. Al-Adha means literally the victims. (Bukhari and Muslim.)
