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.

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!
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.
