How did Prophet Moses and his followers respond to the oppression carried out by King Fir`awn?

Verses 127-129 of Chapter 7:
The chiefs of Fir`awn's people said: "Will you leave Musa and his people to spread mischief in the land, and to abandon you and your gods'' He said: "We will kill their sons, and let their women live, and we have indeed irresistible power over them.'' Musa said to his people: "Seek help in Allah and be patient. Verily, the earth is Allah's. He gives it as a heritage to whom He wills of His servants; and the (blessed) end is for the pious and righteous persons.'' They said: "We suffered troubles before you came to us, and since you have come to us.'' He said: "It may be that your Lord will destroy your enemy and make you successors on the earth, so that He may see how you act''

What is the best garment for human beings?

Verse 26 of Chapter 7:
O Children of Adam! We have bestowed Libas (raiment) upon you to cover yourselves with, and as Rish (adornment); and the Libas (raiment) of Taqwa, that is better. Such are among the Ayat of Allah, that they may remember.

Each of the living creatures has its own community as humans belong to one!

Verse 38 of Chapter 6:
There is not a moving creature on earth, nor a bird that flies with its two wings, but are communities like you. We have neglected nothing in the Book, then unto their Lord they shall be gathered.

Why did God decide hypocrisy for some people?

Verses 1-3 of Chapter 63
When the hypocrites come to you, they say: "We bear witness that you are indeed the Messenger of Allah.'' Allah knows that you are indeed His Messenger, and Allah bears witness that the hypocrites are liars indeed. They have made their oaths a screen. Thus they hinder (others) from the path of Allah. Verily, evil is what they used to do. That is because they believed, and then disbelieved; therefore their hearts are sealed, so they understand not.
