Also verse about performing funeral prayer for the hypocrites. ” O messenger of Allaah, are you about to pray for Abdullah ibn Ubai the man who said such and such on such and such and such day,“  The prophet smiled and continued to perform funeral prayer and Umar showed no sigh of stopping , until the prophet (sallallahu alyhi wasallam) said, "Move back, O Umar. Verily, I have been given a choice (to ask for ibn Ubai’s forgiveness or to not ask for his forgiveness), and I have made my choice. It has been said to me, (Qur'aan 9:80).”

10.  Once two people were disputing so they went to Rasullullah sallAllahu alayhi wasallam to resolve their problem. The Holy Prophet sallAllahu alayhi wasallam gave a decision in favour of one of them. The other said lets go to Hadrath Umar radi Allahu anhu and ask him for a decision. When they arrived at Hadrath Umar radi Allahu anhu the one in whose favour Rasullullah sallAllahu alayhi wasallam had ruled, informed Hadrath Umar radi Allahu anhu that Rasullullah had already adjudicated in his favour but the other person wanted a decision from you. Hadrath Umar radi Allahu anhu went into his room and returned with his sword. He cut off the head of the one who wasn’t happy the verdict of the Holy Prophet sallAllahu alayhi wasallam. The other complainant ran to the Holy Prophet sallAllahu alayhi wasallam and told him what had happened. The Holy Prophet sallAllahu alayhi wasallam that I don’t believe that Hadrath Umar radi Allahu anhu would kill a believer.
The Ayat was revealed, ‘Then O Beloved by your Lord they shall not be Muslims until they make you judge in all disputes among themselves then they find no impediment in their hearts concerning whatever you decide and accept from the eve of their hearts.’ Surah Nisaa verse 65
All this helps us to understand that Hadrath Umar radi Allahu anhu is indeed a blessed personality and his decisions have time and again been certified by the Quran.
