حَدَّثَنَا هُشَيْمٌ أَنْبَأَنَا يَزِيدُ بْنُ أَبِي زِيَادٍ عَنْ مُجَاهِدٍ عَنِ ابْنِ عَبَّاسٍ أَنَّهُ قَالَ أَهَلَّ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ بِالْحَجِّ فَلَمَّا قَدِمَ طَافَ بِالْبَيْتِ وَبَيْنَ الصَّفَا وَالْمَرْوَةِ وَلَمْ يُقَصِّرْ وَلَمْ يَحِلَّ مِنْ أَجْلِ الْهَدْيِ وَأَمَرَ مَنْ لَمْ يَكُنْ سَاقَ الْهَدْيَ أَنْ يَطُوفَ وَأَنْ يَسْعَى وَأَنْ يُقَصِّرَ أَوْ يَحْلِقَ ثُمَّ يَحِلَّ
مسند امام احمد بن حنبل · Hadith 3128
It was narrated that Ibn 'Abbas (RA) said: The Prophet (PBUH) entered ihram for Hajj . When he arrived he circumambulated the Ka'bah and went between as-Safa and al-Marwah, but he did not cut his hair or exit ihram because of the hady. But he ordered those who had not brought the hady to circumambulate (the Ka'bah) and perform sa'y, and to cut their hair or shave their heads, then exit ihram.
