According to the Sunnees, this hadeeth is Da'eef (Weak)but did Umar not heard about Prophet Õáì Çááå Úáíå æÂáå saying, “Seek knowledge even if you have to travel to China".
اطلبوا العلم ولو بالصين ، فإن طلب العلم فريضة على كل مسلم
“Seek knowledge even if you have to go as far as China, for seeking knowledge is a duty on every Muslim,”
Al-Albaani has talked about this extensively (9 pages long just on this hadeeth) in his book, and his conclusion is this hadeeth Da'eef
- Al-Albaani, Silsalah Al-aHaadeeth Al-Da'eefah wa Al-MawDoo'ah, vol. 1, pg. 600 - 609, hadeeth # 416
There is mention of this hadeeth in some of our books, but this hadeeth is sanad-less (no chain of narrators), so it'll be Da'eef according to us as well.
