Bism Illah wa as salaamu alaykum wa Rahmat Allah wa Barakatuh.
This is a post that may have a sequel, however hubby and I have sat and composed this to address the outlook and reality for others who desire to make hijrah to Muslim countries, and to Saudi Arabia - Makkah/Madinah specifically.
It is important to think about the meaning of hijrah and whether the place you move to is somewhere you will be able to stay or not. When we got on the plane to move to Madinah, we came with the understanding that this isn't our country and that with the immigration laws so difficult here, it isn't likely we will be able to live here forever. Anyone who comes here, unless they are a national of the country, can end up leaving at any time. Even if you are a national, your citizenship can be revoked.
It isn't wise to put all your eggs in one basket. Ideally if we could live here and do all the things we want to do in the States here, and have the assurance that things could go without trouble then we would stay. However, we are expats - here to work. Once we don't work or aren't of any service to the government or private sector, there is no compelling reason to keep us here. Unlike the countries we are from, we are very familiar with the job market, retirement, and things needed to live but we don't have the fear of being kicked out of our own country.
If we look at the life of the sahaba (radhi Allahu anhum), we see that very few of them are buried in Madinah. They scattered throughout the world giving da'wah. How can we justify living in a land that is not ours after we have acquired knowledge? Shouldn't we go back and benefit the people that are like us and didn't have the opportunity we had?
For a scholar who was born and raised in Saudi Arabia to come to the United States or the UK for example and give da'wah to educate the people, it would very difficult. He is not familiar with the common problems in Western society, such as drug abuse, blended families, deviant racist branches of so-called Islam and a whole style of life that is not conducive to Islam. However, we are from these lands, we know the problems such as when the Muslim drug addict comes to the masjid and steals the money from the zakat box...or the woman who is a stripper during the evening but attends the masjid for jumu'ah. The simple answer that the scholars give of "fear Allah" is not what the hearts of these people need. However, those who have lived amongst those people have a better understanding of the trials and tribulations they go through. In that respect we are better suited to help the negative nature of these Muslims and help them strive towards the straight and narrow path.
If I sit in Saudi, who am I giving da'wah to? Who am I teaching? For us, it is a life of service and you cannot serve until you learn, so this is our school.
