What are the most important rights that are respected in Islam?

I hope you can give me some examples of good deeds that we can do every day to increase our hasanaat.

1. I would like to know the dividing line between hypocrisy and courtesy, because in many cases I feel that there is some two-facedness in people's behaviour and dealings, based on their interests and whims and desires, and it is said that it is just courtesy. Is this true? 

2. Is it possible for true friendship to be mixed with a little hypocrisy? I have a friend who does not love me as I thought she did. She held a special place in my heart that was shared by no one else, but recently I found out that my status with her is zero, and her behaviour with me for many years was superficial. I thought, and everyone was certain about that, that our friendship was strong, and until now I do not know how to end this friendship after finding out what is really going on. 

3. Can the way this friend behaved be regarded as hypocrisy? 

4. What is the punishment for hypocrisy in friendship?

If one Muslim brother loves another Muslim brother, does he have to say to this brother "I love you for the sake of Allah?

Some scholars of tajweed said that it is obligatory to read Qur'aan with the rules of tajweed. Is that true?

I am from a Muslim background, but I never used to offer the obligatory prayers and even when I tried to pray once, I did not do it right. In other words I did not prepare to do it in the proper manner. I ask Allah to forgive me. I heard that the one who does not pray is a disbeliever and is not a Muslim, but whoever offers the five daily prayers, or one or two of them and omits the rest, is regarded as a Muslim. Also, I did not pay zakah on my wealth, but for at least two years I have completed the fast of Ramadan, and I intend to continue doing so. I want to learn how to pray and make it part of my life, along with other acts of worship. 

Is it obligatory for me to pay zakah for all these many years (when I did not pay it), and to make up the days that I did not fast at the time when I was not praying? 

Please note that I have now reached the age of thirty-one years; perhaps you will understand that this may cause me a great deal of hardship; to ward off that hardship, can I start over? Will Allah forgive me if I do that?

could you please advise us about how improve our manners, and raise our children to have good manners? As many of the scholars mentioned, they studied under their teachers for years to learn proper manners. I am very concerned because it seems that we are surrounded by bad examples and role models, and the standards of society are very low. I am a revert to Islam so I was not raised with good Islamic manners. I don't have the knowledge or training to be a very good role model. My childrens TV watching is very restricted, but they still interact with cousins and friends who pick up bad words and attitudes from TV. We also educate our children at home. But as much as we shelter them and instruct them, they seem to pick up some of the attitudes of the greater society. I am torn between whether I should continue trying to remain patient and remind them gently, or I should become more strict to enforce better behavior. We would really appreciate any advice that you could offer.

A woman became Muslim and lives with her family who are not Muslims, and now they do not object to her being Muslim. She tried to call them to Islam by various means, but to no avail. How should she deal with them in their misguided state? Should she uphold ties with them or limit her relationship with them?.

A man lives within a community that commits shirk (polytheism) by appealing for help from other than Allah. Is he allowed to pray with them with their leading the prayer? Is it obligatory to abandon them? Is their Shirk considered shirk al-akbar (great and serious act of disbelief by associating other beings with Allah's supremacy)? Is alliance with them treated the same as alliance with true non-believers?

I have a question regarding the permissibility of becoming a law enforcement officer in this country that does no follow sharee 'ah. Is it haraam to be enforcing laws that have not been developed by our Creator Allaah and His holy Prophets (upon whom be peace)? Even if it means enforcing laws on non-Muslims?

Partciluarly, is it permissible to enforce a law like punishing someone for speeding on the highway? What about allowing someone to drink alcohol if he is over 21 but not if he is under 21? Even though this is not Islamic, should a Muslim allow such behaviour among non-Muslims? Of course, Muslims will be accountable for these haraam actions in the Hereafter, but is it okay to let non-Muslims do this?

Can muslims accept donations from non-muslims to use in Islamic Cause?

How merciful is Allah, because I heard he loves you more than 70 mothers. Is that true? Please explain?
