Can Dua change destiny in relation to matters like marriage, work, and the like?

The Muslim who believes in the Law of Islam, the prescribed prayer and fasting sometimes says to himself, for example, : "I wish Allah hadn`t prescribed or revealed prayer and fasting." He says this out of laziness, fatigue, and the hardship involved in fasting." Such a person doesn`t mean to degrade Islam or fight it; rather, he loves comfort and avoids fatigue. In light of this, does the verse "That is because they hate the Revelation of God; so He has made their deeds fruitless."{Mohammad, 9} apply to this person? Is this considered greater Kufr that drives him out of the fold of Islam and makes him an apostate?

Is there an evidence from Sharia for dividing Tawheed into three categories: Tawheed Al-Uloohiyah(Oneness of the Divine Nature), Tawheed Al-Ruboobiyyah(Oneness of the Divine Lordship), and Tawheed Al-Asma`wa`l-Sifat(Oneness of the Divine Names and Attributes)?

Ruling on reporting words of disbelief, such as saying that someone said "So and so", and reviled the religion. Does the reporter of this become a disbeliever (Kafir)?

Some of the books that I have read stated that Allah exists, but we can`t know Him through intellectual evidence, and it suffices to have a conviction in one`s heart that He exists. Frankly, I`m convinced with this and will be morally committed to it to the letter. My question is: Does having an inner conviction in the existence of God, without having actual evidence, suffice as proof that a Muslim believes in God, and will be admitted to paradise as a result?

What`s the ruling on preferring Ali Bin Abi Talib (May Allah be pleased with him) over the rest of the Companions (May Allah be pleased with them), including Abu Bakr and Umar (May Allah be pleased with them), but without criticizing any or calling them bad names?

How could you answer those who say that rituals of Islamic pilgrimage are pagan practices?

I am a mother of a student in the second grade. While teaching him, I noticed that the lesson about Prophet Ibrahim (PBUH) included a text which says that idols are creatures that neither harm nor profit. Is it correct to describe idols as creatures? Aren't they made of stone and the stone is the created? Aren't they man-made ? How could we call what man made a creature? Could we call the computer, the refrigerator and the house creatures?
