ولقد أرسلنا رسﻼ من قبلك منهم من قصصنا عليك
And, indeed We have sent Messengers before you, of some of them We have related to you their story.
as Allah also says in Surah An-Nisa', meaning, `We have revealed the stories of some of them and how their people disbelieved in them, but the Messengers ultimately prevailed.'
ومنهم من لم نقصص عليك
And of some We have not related to you their story,
and they are many, many more than those whose stories have been told, as has been stated in Surah An-Nisa'.
Praise and blessings be to Allah.
وما كان لرسول أن يٲتي باية إﻻ بٳذن الله
and it was not given to any Messenger that he should bring a sign except by the leave of Allah.
means, none of the Prophets was able to bring miracles to his people except when Allah granted him permission to do that as a sign of the truth of the message he brought to them.
فٳذا جاء أمر الله
But, when comes the commandment of Allah,
means, His punishment and vengeance which will encompass the disbelievers,
قضي بالحق
the matter will be decided with truth,
so the believers will be saved and the disbelievers will be destroyed.
Allah says:
وخسر هنالك المبطلون
and the followers of falsehood will then be lost
