1st Muharram reminds of martyrdom of 2nd Caliph and father in law of Rasool Allah SAW Umer the great.
Umer radi Allaho anho was true follower of Prophet SAW who always submitted before command of Rasool salal laho aliehi wasalam.
Umer radi Allaho anhu was great conqueror and was able to establish Islamic law on more than 2200000 square miles. He was great administrator who consistently checked the efficiency of his appointed governors. His effective judicial system is even praised by orientalists.
He led a simple life and was never trapped by worldly desires. His love for prophet salal laho aliehi wasalam and city of Madina is marvelous aspect of his personality. He wished to die in land as martyr and wanted burial in Medina. Allah swt fulfilled his both wished and he was able to die as martyr and was buried beside prophet salal laho aliehi wasalam.
May Allah be pleased with Ameer ul Momineen Umer radi Allahu anhu and shower His blessings on his grave till the day of Judgement Ameen.
