Excerpts from the Al-Quran

Why a good thing can be bad for you, vice versa? 
Surah Al-Baraqah 2:216 Sahih International 
Fighting has been enjoined upon you while it is hateful to you. But perhaps you hate a thing and it is good for you; and perhaps you love a thing and it is bad for you. And Allah Knows, while you know not.

Why it is not good to marry poltheistic people? 
Surah Al-Baraqah 2:221 Sahih International 
And do not marry polytheistic women until they believe. And a believing slave woman is better than a polytheist, even though she might please you. And do not marry polytheistic men [to your women] until they believe. And a believing slave is better than a polytheist, even though he might please you. Those invite [you] to the Fire, but Allah invites to Paradise and to forgiveness, by His permission. And He makes clear His verses to the people that perhaps they may remember.

How you want is up to you, with exception of what is explicitly forbidden? 
Surah Al-Baraqah 2:223 Sahih International 
Your wives are a place of sowing of seed for you, so come to your place of cultivation however you wish and put forth [righteousness] for yourselves. And fear Allah and know that you will meet Him. And give good tidings to the believers.

What is the precautionary period before a divorce?
Surah Al-Baraqah 2:226 Sahih International 
For those who swear not to have sexual relations with their wives is a waiting time of four months, but if they return [to normal relations] - then indeed, Allah is Forgiving and Merciful.

If what Allah hates most is divorce, is it permissible?
Surah Al-Baraqah 2:227 Sahih International 
And if they decide on divorce - then indeed, Allah is Hearing and Knowing.

Can a government agency impose a person to choose a religion not of that person's choice?
Surah Al-Baraqah 2:256 Sahih International 
There shall be no compulsion in [acceptance of] the religion. The right course has become clear from the wrong. So whoever disbelieves in Taghut and believes in Allah has grasped the most trustworthy handhold with no break in it. And Allah is Hearing and Knowing.

Does spending of your wealth get His blessing? 
Surah Al-Baraqah 2:261 Sahih International 
The example of those who spend their wealth in the way of Allah is like a seed [of grain] which grows seven spikes; in each spike is a hundred grains. And Allah multiplies [His reward] for whom He wills. And Allah is all-Encompassing and Knowing.

What is better than charity?
Surah Al-Baraqah 2:263 Sahih International 
Kind speech and forgiveness are better than charity followed by injury. And Allah is Free of need and Forbearing.

What is Satan's plan of strategy?
Surah Al-Baraqah 2:268 Sahih International 
Satan threatens you with poverty and orders you to immorality, while Allah promises you forgiveness from Him and bounty. And Allah is all-Encompassing and Knowing.

Who get's His wisdom?
Surah Al-Baraqah 2:269 Sahih International
He gives wisdom to whom He wills, and whoever has been given wisdom has certainly been given much good. And none will remember except those of understanding.

Give in private is best
Surah Al-Baraqah 2:271 Sahih International 
If you disclose your charitable expenditures, they are good; but if you conceal them and give them to the poor, it is better for you, and He will remove from you some of your misdeeds [thereby]. And Allah , with what you do, is [fully] Acquainted.

What Allah thinks of interest
Surah Al-Baraqah 2:276 Sahih International 
Allah destroys interest and gives increase for charities. And Allah does not like every sinning disbeliever.

You did it to yourself
Surah Al-Baraqah 2:286 Sahih International 
Allah does not charge a soul except [with that within] its capacity. It will have [the consequence of] what [good] it has gained, and it will bear [the consequence of] what [evil] it has earned. "Our Lord, do not impose blame upon us if we have forgotten or erred. Our Lord, and lay not upon us a burden like that which You laid upon those before us. Our Lord, and burden us not with that which we have no ability to bear. And pardon us; and forgive us; and have mercy upon us. You are our protector, so give us victory over the disbelieving people."

How and why you are who you are?
Surah Al-Imran 3:6 Sahih International 
It is He who forms you in the wombs however He wills. There is no deity except Him, the Exalted in Might, the Wise.

What is the religion of Allah?
Surah Al-Imran 3:19 Sahih International 
Indeed, the religion in the sight of Allah is Islam. And those who were given the Scripture did not differ except after knowledge had come to them - out of jealous animosity between themselves. And whoever disbelieves in the verses of Allah, then indeed, Allah is swift in [taking] account.

Surah Al-Imran 3:59 Sahih International 
Indeed, the example of Jesus to Allah is like that of Adam. He created Him from dust; then He said to him, "Be," and he was.

Surah Al-Imran 3:137 Sahih International 
Similar situations [as yours] have passed on before you, so proceed throughout the earth and observe how was the end of those who denied.

Surah Al-Imran 3:140 Sahih International 
If a wound should touch you - there has already touched the [opposing] people a wound similar to it. And these days [of varying conditions] We alternate among the people so that Allah may make evident those who believe and [may] take to Himself from among you martyrs - and Allah does not like the wrongdoers

Surah Al-Imran 3:142 Sahih International 
Or do you think that you will enter Paradise while Allah has not yet made evident those of you who fight in His cause and made evident those who are steadfast?

Your death is decided divinely
Surah Al-Imran 3:145 Sahih International 
And it is not [possible] for one to die except by permission of Allah at a decree determined. And whoever desires the reward of this world - We will give him thereof; and whoever desires the reward of the Hereafter - We will give him thereof. And we will reward the grateful.

Surah Al-Imran 3:165 Sahih International 
Why [is it that] when a [single] disaster struck you [on the day of Uhud], although you had struck [the enemy in the battle of Badr] with one twice as great, you said, "From where is this?" Say, "It is from yourselves." Indeed, Allah is over all things competent

You are constantly being tested
Surah Al-Imran 3:187 Sahih International 
You will surely be tested in your possessions and in yourselves. And you will surely hear from those who were given the Scripture before you and from those who associate others with Allah much abuse. But if you are patient and fear Allah - indeed, that is of the matters [worthy] of determination.

Surah Al-Imran 3:200 Sahih International 
O you who have believed, persevere and endure and remain stationed and fear Allah that you may be successful.

Surah An-Nisa 4:3 Sahih International 
And if you fear that you will not deal justly with the orphan girls, then marry those that please you of [other] women, two or three or four. But if you fear that you will not be just, then [marry only] one or those your right hand possesses. That is more suitable that you may not incline [to injustice].

Surah An-Nisa 4:4 Sahih International 
And give the women [upon marriage] their [bridal] gifts graciously. But if they give up willingly to you anything of it, then take it in satisfaction and ease.

Do not give away your property to the 'weak minded'
Surah An-Nisa 4:5 Sahih International 
And do not give the weak-minded your property, which Allah has made a means of sustenance for you, but provide for them with it and clothe them and speak to them words of appropriate kindness.

How to distribute property?

Surah Al-Imran 4:11 Sahih International 
Allah instructs you concerning your children: for the male, what is equal to the share of two females. But if there are [only] daughters, two or more, for them is two thirds of one's estate. And if there is only one, for her is half. And for one's parents, to each one of them is a sixth of his estate if he left children. But if he had no children and the parents [alone] inherit from him, then for his mother is one third. And if he had brothers [or sisters], for his mother is a sixth, after any bequest he [may have] made or debt. Your parents or your children - you know not which of them are nearest to you in benefit. [These shares are] an obligation [imposed] by Allah . Indeed, Allah is ever Knowing and Wise.
