عَنِ ابْنِ عَبَّاسٍ رَضِيَ اللَّهُ عَنْهُمَا عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ كُتِبَ عَلَيَّ النَّحْرُ وَلَمْ يُكْتَبْ عَلَيْكُمْ وَأُمِرْتُ بِرَكْعَتَيِ الضُّحَى وَلَمْ تُؤْمَرُوا بِهَا
It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: Sacrifice has been made obligatory upon me, and it has not been made obligatory upon you; similarly, I have been commanded to perform two rak‘ahs of Duha prayer, and you have not been commanded to perform them.
