Who said the last part of "Bukhari 2287," Umar (رضي الله عنه) or our beloved Prophet (صلى الله عليه واله وسلم)?

In the following hadith: > ‘Umar ibn al-Khattaab who said: “I heard Hishaam ibn Hakeem reciting Soorat al-Furqaan in a manner different from that in which I used to recite it and the way in which the Messenger of Allaah (peace and blessings of Allaah be upon him) taught me to recite it. I was about to argue with him whilst he was praying, but I waited until he finished his prayer, and then I tied his garment around his neck and seized him by it and brought him to the Messenger of Allaah (peace and blessings of Allaah be upon him) and said, ‘O Messenger of Allaah, I heard this man reciting Soorat-al-Furqaan in a way different to the way you taught it to me.’ The Messenger of Allaah (peace and blessings of Allaah be upon him) said to him, ‘Recite it,’ and he recited it as I had heard him recite it. The Messenger of Allaah (peace and blessings of Allaah be upon him) said, ‘It was revealed like this.’ Then he said to me, ‘Recite it,’ so I recited it and he said, ‘It was revealed like this.’ This Qur'aan has been revealed in seven different ways, so recite it in the way that is easiest for you.’” (Narrated by al-Bukhaari, 2287; Muslim, 818) ln the part where one of them says: > This Qur'aan has been revealed in seven different ways, so recite it in the way that is easiest for you. Who said it? Umar (رضي الله عنه) or the Prophet (صلى الله عليه واله وسلم)? Jazakum Allah khayran
