The Messenger of Allah (sal Allahu alaihi wa sallam) said: “Whoever neglects the Asr Prayer will have his (good) deeds nullified.” [Bukhari]
Once Umar (radi Allahu anhu) went to his orchard. By the time he came back the congregational Prayer of Asr was over. He was very upset at this misfortune and uttered the exclamation of adversity, “Surely we belong to Allah and surely to Him will we return.” Thereafter he said, “May you people be witness that I give my garden in charity to the needy so as to expiate what I have done (missing the Prayer in congregation).”
May Allah (subhana wa ta’ala) grant us even a fraction of this Eeman.
