﴿إِنَّا لَنَنصُرُ رُسُلَنَا وَالَّذِينَ ءَامَنُواْ فِى الْحَيَوةِ الدُّنْيَا﴾

(Verily, We will indeed make victorious Our Messengers and those who believe in this world's life). As-Suddi, "Allah never sends a Messenger to a people and they kill him or some of the believers who call them to the truth, then that generation passes away, but He then sends them someone who will support their call and will seek vengeance for their blood from those who did that to them in this world. So the Prophets and believers may be killed in this world, but their call will prevail in this world.'' Allah granted victory to His Prophet Muhammad and his Companions over those who had opposed him, disbelieved in him and shown hostility towards him. He caused His Word and His religion to prevail over all other religions, commanded him to emigrate from his people to Al-Madinah, where He gave him supporters and helpers. Then He caused him to prevail over the idolators on the day of Badr, when He granted him victory over them and he humiliated them, killing their leaders and taking their elite prisoner, driving them before him in chains. Then he did them the favor of accepting ransom from them. Shortly after that, Allah enabled him to conquer Makkah, and he rejoiced in his return to his homeland, the sacred and holy land of Al-Haram. Through him, Allah saved it from its disbelief and Shirk. Then Allah enabled him to conquer the Yemen, and the entire Arabian Peninsula submitted to him, and the people entered the religion of Allah in crowds. Then Allah took him (in death), because of his high status and honor, and He established his Companions as his Khalifahs. They conveyed the religion of Allah from him, called mankind to Allah, they conquered many regions, countries and cities, and opened people's hearts, until the call of Muhammad spread throughout the world, east and west. This religion will continue to prevail until the Hour begins. Allah says:

﴿إِنَّا لَنَنصُرُ رُسُلَنَا وَالَّذِينَ ءَامَنُواْ فِى الْحَيَوةِ الدُّنْيَا وَيَوْمَ يَقُومُ الاٌّشْهَـدُ ﴾

(Verily, We will indeed make victorious Our Messengers and those who believe in this world's life and on the Day when the witnesses will stand forth) meaning, on the Day of Resurrection the victory will be greater and more complete. Mujahid said, "The witnesses are the angels.''

﴿يَوْمَ لاَ يَنفَعُ الظَّـلِمِينَ مَعْذِرَتُهُمْ﴾

(The Day when their excuses will be of no profit to wrongdoers.) is referring to the same as;

﴿وَيَوْمَ يَقُومُ الاٌّشْهَـدُ﴾

(...the Day when the witnesses will stand forth.) Others read it with that meaning;

﴿وَيَوْمَ يَقُومُ الاٌّشْهَـدُيَوْمَ لاَ يَنفَعُ الظَّـلِمِينَ﴾

(And the Day the witnesses will stand forth, is a Day when there will be no profit to wrongdoers.) and the wrongdoers are the idolators.

﴿مَعْذِرَتُهُمْ﴾

(their excuses) means, no excuse or ransom will be accepted from them.

﴿وَلَهُمُ الْلَّعْنَةُ﴾

(Theirs will be the curse,) means, they will be cast out far away from the mercy of Allah.

﴿وَلَهُمْ سُوءُ الدَّارِ﴾

(and theirs will be the evil abode.) means, the Hell-fire, as As-Suddi said, a terrible abode and dwellingplace.
