Nay,-whoever submits His whole self to Allah and is a doer of good,- He will get his reward with his Lord; on such shall be no fear, nor shall they grieve.
According to Muhammad Amin A. Samad,
‘This statement is the reminiscent of Allah’s promise to Adam and Eve after accepting their repentance for eating the forbidden fruit. He said:
“(For although) We did say, ‘Down with you all from this (state),’ there shall, none the less, most certainly come unto you guidance from Me: and those who follow My guidance need have no fear, and neither shall they grieve; but those who are bent on denying the truth and giving the lie to Our messages ‐ they are destined for the fire, and therein shall they abide.”
(Qur’ān 2: 38‐39, Asad’s translation)
This verse indicates the continuation of Allah’s guidance to mankind through His messengers since the time of Adam till the Last Day. This message reached its culmination in Prophet Muhammad (s.a.w.) who was the last messenger and was sent to the whole of mankind.
