Ibn `Abbas reported God s messenger as saying, "Sacrifice was prescribed for me but not for you, and I was ordered to observe prayer in the forenoon but you were not." Daraqutni transmitted it.
وَعَنِ ابْنِ عَبَّاسٍ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «كُتِبَ عَلَيَّ النَّحْرُ وَلَمْ يُكْتَبْ عَلَيْكُمْ وَأُمِرْتُ بِصَلَاةِ الضُّحَى وَلَمْ تؤمَروا بهَا» . رَوَاهُ الدَّارَقُطْنِيّ
