All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger. We ask Allaah to exalt his mention as well as that of his family and all his companions.
Ibn 'Umar is one of the companions who narrated a great number of Prophetic narrations.
Indeed, Ibn Al-'Imaad, Al-Hanbali stated that Imaam Ath-Thahabi said: "The companions who narrated a great number of Prophetic narrations, are Abu Hurayrah who narrated 5374 narrations, Ibn 'Umar who narrated 2630 narrations, and Anas who narrated 2276 narrations…"
Therefore, it becomes clear that the number of Prophetic narrations which were narrated by Ibn 'Umar were 2630.
Allaah Knows best.
