Those will have lost who deny the meeting with Allah, until when the Hour [of resurrection] comes upon them unexpectedly, they will say, "Oh, [how great is] our regret over what we neglected concerning it [i.e., the Hour]," while they bear their burdens [i.e., sins] on their backs. Unquestionably, evil is that which they bear.
1 Mufti Taqi Usmani
Losers indeed are those who deny that they will ever face Allah, until when the Hour will come upon them suddenly, they will say, “Alas! We have been negligent about it.” They shall carry their burdens on their backs. Beware! Evil is the burden they carry.
