COMMENTARY on 41:43
A. Yusuf Ali:

Translation:
Nothing is said to you that was not said to the messengers before you: 4515 that your lord has at his Command (all) forgiveness as well as a most Grievous Penalty.
Commentary:

4515  The gist of Allah's Message, now, before, and for ever, is the same: Mercy to the erring and repentant; just punishment to those who wilfully rebel against Allah.

 

Muhammad Asad:

Translation:
[And as for thee, O Prophet,] nothing is being said to thee but what was said to all [of God’s] apostles before thy time. 36 Behold, thy Sustainer is indeed full of forgiveness - but He has also the power to requite most grie­vously!
Commentary:
36  This is an allusion to the allegation of the Prophet’s opponents that he himself was the "author" of what he claimed to be a divine revelation, as well as to their demand that he should "prove" the truth of his prophetic mission by producing a miracle: a scornful attitude with which all the earlier prophets had been confronted at one time or another, and which is epitomized in the "saying" of the unbelievers mentioned in verse 5 of this surah.
