Meaning:-
Avert: to turn away or aside:

As for those who believe and do good deeds and believe in what is revealed to Muhammad – the truth from their Lord – He will remove from them their evils and improve their condition.

Meaning:-
Falsehood: lie, untruth

So when you meet in battle those who disbelieve, then smite the necks until when you have overcome them, then make (them) prisoners, and afterwards either set them free as a favor or let them ransom (themselves) until the war terminates. That (shall be so); and if Allah had pleased He would certainly have exacted what is due from them, but that He may try some of you by means of others; and (as for) those who are killed in the way of Allah, He will by no means allow their deeds to perish.
Meaning:-
Smite: to strike
Perish: disappear, vanish,

Soon He will guide them, improve their condition

That is because they hate that which Allah has sent down (this Quran and Islamic laws, etc.), so He has made their deeds fruitless.

Have they not traveled through the land and seen how was the end of those before them? Allah destroyed [everything] over them, and for the disbelievers is something comparable.

That is because Allah is the protector of those who have believed and because the disbelievers have no protector.

Surely Allah will admit those who believe and do good deeds to gardens beneath which rivers flow. While those who are unbelievers, they are to enjoy only this life and eat as cattle eat; but in the hereafter, the fire shall be their abode.

Abode: a place in which a person resides, home,

So is he who is on clear evidence from his Lord like him to whom the evil of his work has been made attractive and they follow their [own] desires?

Is the description of Paradise, which the righteous are promised, wherein are rivers of water unaltered, rivers of milk the taste of which never changes, rivers of wine delicious to those who drink, and rivers of purified honey, in which they will have from all [kinds of] fruits and forgiveness from their Lord, like [that of] those who abide eternally in the Fire and are given to drink scalding water that will sever their intestines?

And among them, [O Muhammad], are those who listen to you, until when they depart from you, they say to those who were given knowledge, “What has he said just now?” Those are the ones of whom Allah has sealed over their hearts and who have followed their [own] desires.

And (as for) those who follow the right direction, He increases them in guidance and gives them their guarding (against evil).

Then do they await except that the Hour should come upon them unexpectedly? But already there have come [some of] its indications. Then what good to them, when it has come, will be their remembrance?

Decisive: producing a definite result.
Woe: great sorrow or distress.

Obedience and good words. And when the matter [of fighting] was determined, if they had been true to Allah , it would have been better for them.

Would you then, if you were given the authority, do mischief in the land, and sever your ties of kinship?
Meaning:-

Such are they whom Allah has cursed, so that He has made them deaf and blinded their sight.

Do they not then think deeply in the Quran, or are their hearts locked up (from understanding it)?

Those who turn back to unbelief after the guidance has become clear are seduced by Shaitan who gives them false hopes.
Meaning:-
Seduced: Tempt, attract powerfully.

This, because they said to those who hate what Allah has revealed, “We will obey you in part of (this) matter”; but Allah knows their (inner) secrets.

Surely those who disbelieve and turn away from Allah’s way and oppose the Messenger after that guidance has become clear to them cannot harm Allah in any way, and He will make their deeds fruitless.
