you are right but unfortunately most of the fellow guppies here either can not see the obvious or are avoiding it intentionally. I guess everytime Khalifa Umar disobeyed the Prophet of Allah, he seemed had “the best intentions in mind as he didnt want to see the Muslims in a weak position”! So Khalifa Umar knew better what would make Muslims weak and the Prophet of Allah perhaps did not!
Below are some more achievements of the Khalifa Umar, all from Saha Sitta, i.e. the most authentic book of hadiths. Enjoy!
