ذِكْرُ الْخَبَرِ الدَّالِّ عَلَى أَنَّ الْأُضْحِيَّةَ اسْتِعْمَالُهَا غَيْرُ فَرْضٍ
that Messenger of Allah ﷺ said: "If anyone of you has seen the crescent of Dhū al-Ḥijjah and one of you want to offer a sacrifice ˹on the Day of Naḥr˺, then he should hold back ˹cutting˺ his hair and nails." (Using translation from Muslim 1977e)
عَنِ النَّبِيِّ ﷺ قَالَ «إِذَا رَأَى أَحَدُكُمْ هِلَالَ ذِي الْحِجَّةِ وَأَرَادَ أَنْ يُضَحِّيَ فَلْيُمْسِكْ عَنْ شَعْرِهِ وَأَظْفَارِهِ»
