Does falling into sin indicate that there is something wrong with one's 'aqeedah (belief system)?

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?

What is the definition of gheebah and what is the ruling on it?

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?

I am a young Muslim man who believes in Allah and His Messengers and His Books, praise be to Allah. But sometimes I feel too lazy to pray. I am looking for a solution and a way to make me not be so lazy. Please note that this is what I want but the tricks of the Shaytaan are too strong.

I was just wondering if someone says he will drink and do zina (fornicate) and do haram (unlawful) stuff and then he will repent, will his repentance be accepted?

What are the signs of Allah's love for His slave?

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.

Firstly: I apologize for asking such a question, and so that there will be no room for doubt about my intention I will say that I bear witness that there is no god but Allaah and that Muhammad is the Messenger of Allah, and I am completely content with Allah as my Lord, Islam as my religion and Muhammad (peace and blessings of Allah be upon him) as my Prophet.   

I am asking about the Sunnah, because there are many reports of a single hadith. For example, we may find in Saheeh al-Bukhaari a hadith that appears in a form different than that in which it appears in Saheeh Muslim. Why isn't the Sunnah like the Holy Qur'aan? What is the difference between the Sunnah and the Holy Qur'aan? Is the Sunnah part of the Wahy that was revealed to the Messenger (peace and blessings of Allah be upon him) or is it just his words and deeds? Is it one of the characteristics of Prophethood or what?

Is it true that anyone who does not accept that kuffaar are kuffaar is a kaafir himself, even if he prays, believes in the Qur'aan, and the Prophet Muhammad? If so, what is the proof for this? Can a person insist on believing that Jews and Christians can be believers and go to heaven after being shown clear evidence against this, and still be considered a Muslim?

My neighbour is an American Christian, and she and her family brought me a gift when it was Christmas. I could not refuse the gift, lest she be offended.  
Can I accept this gift, as the Messenger (peace and blessings of Allaah be upon him) accepted gifts from kaafirs?
