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

I would like to know the proper way to make du’aa’ during prayer, as the Prophet (peace and blessings of Allaah be upon him) did it. Is it after the prayer or between the two prostrations or whilst standing or when?.

When I went to do ‘umrah, I was menstruating, so I did sa‘i and cut my hair, and I exited ihram and put on niqab. I waited until I became pure, then I did tawaaf at the Ka‘bah. I did this based on the ruling on Hajj, which says that the menstruating woman should do everything except tawaaf. Please note that I am not married. What is your opinion, may Allah bless you?

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

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?

Who do Muslims worship?

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?.

Is it permissible to eat food that is distributed on the birthday of the Prophet Muhammad (peace and blessings of Allaah be upon him)? Some people quote as evidence the idea that because Abu Lahb set free a slave woman on the birthday of the Prophet (peace and blessings of Allaah be upon him), Allaah reduced the torment for him on that day.

Is it permissible to pray in a mosque where the ground floor is controlled by the Shi‘ah and the Sunnis control the upper floor?

Is it true that the person who is used to studying in Islamic schools, and has no previous experience of studying in non-Islamic schools, will never be able to connect with the environment that surrounds him, where most of the people are non-Muslims and that he will grow up shy and will never find any way to succeed either in his academic life or in the workplace? What is your opinion about that?
