مُسْنَدُ أَحْمَدَ
Musnad Ahmad 3104
Musnad of 'Abdullah bin al-'Abbas bin 'Abdul-Muttalib from the Prophet
It was narrated that Ibn ‘Abbas (رضي الله عنه) said: The Prophet (ﷺ) 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.
