I am doing research on the concept of monotheism in the world's five major religions. Could you please explain to me the concept of monotheism in Islam?
 

What is the difference in meaning between Allah's names al-Rahman and al-Rahim?
 

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

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

What is the Islamic ruling on the issue of imitating the kuffaar in their customs and dealings? What are the guidelines concerning that in Islamic sharee'ah? Is every imitation of the actions of the kuffaar regarded as a haraam kind of imitation, knowing that there are many things that the kaafirs do that are not haraam and are not condemned by sharee'ah, where the one who does them does not do them merely to imitate the kuffaar, but because he thinks those things are good, as Ibn Mas'ood (may Allah be pleased with him) said: "What the Muslims think is good is good before Allah"?  
Please advise us, may Allah honour you, and please give me a detailed answer and explain to me the guidelines on this matter.

I have read the many pages of your web site that instructs a non-believer. I believe that there is only Allah (one God). Ibelieve that Muhammed is the seal of the prophets. History bears this out. My question is: How do I declare this (shahadah) if I do not speak arabic?  How do I perform the five daily prayers (salah) without understanding arabic? Finally would I have to change my name?

What advice can you give to the Muslims in the west in the current situation in which the Muslim ummah finds itself? How can we fulfil our Islamic duties and please Allaah?.

I am currently living in Canada for the purpose of study, but my permanent place of residence is between Jeddah and Amman. When I stayed in Amman during the summer break, I decided to go to Jeddah to deal with some official papers, and I intended to do ‘umrah if Allah made that possible for me and if I had a mahram and enough time to do ‘umrah. I intended to do ‘umrah from Jeddah because my mahram would be there. But because I was not certain that I would be able to do ‘umrah, on the day I travelled by plane I did not do ghusl, because I was menstruating and I had not yet decided to do ‘umrah. When I got there on the second day I did ghusl and formed the intention to do ‘umrah from Jeddah, and I did it.
My questions are:
Is my ihram from the miqaat of Jeddah considered valid or not?  Because of my family circumstances, we are always moving back and forth between Jeddah and Amman, and we always enter ihram from our house in Jeddah, even if we are on our way back from a trip to Amman and after staying in Jeddah for several days. We do not remember how many times we have done ‘umrah in this manner.
What is required of us if we should have entered ihram from the miqaat for the people of ash-Shaam (Greater Syria)? After I did ‘umrah I was uncertain as to whether I was completely clean following my period. If I think it most likely that I was still menstruating whilst I was doing ‘umrah, what is the ruling on my ‘umrah and what expiation do I have to offer?.

What is sincerity, and what are the benefits of sincerity?

Some mobile phones have a Quraan programs which enable one to read the Quraan anytime on the mobile’s screen. Is Taharah (Purity) a condition before one starts reciting?.
