Question:
As salamu aleykumI live in Germany and i can practice my religion here freely. I know that mixing genders is haraam, but the schools here are generally mixed. I dont want to marry and have children because of that. But my family urges me to marry, because it is better when a righteous person has children they say. And I dont want to migrate just to have an family. What should I do?
Answer:
All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad 
is His slave and Messenger.
Your fear of having children who may be exposed to some of the challenges in those countries should not prevent you from getting married. Sharee'ah strongly encourages one to get married, because of the many benefits and interest that it entails, such as preserving your chastity and that of a Muslim woman, in which is a great reward. It was reported in Saheeh Muslim that the Messenger of Allah said: “…and in man's sexual intercourse (with his wife) there is a Sadaqah.” They (the Companions) said: “O Messenger of Allah, is there reward for him who satisfies his sexual passion among us?” He said: “Tell me, if he were to devote it to something forbidden, would it not be a sin on his part? Similarly, if he were to devote it to something lawful, he should have a reward.” [Muslim]. This is in addition to the fulfillment of your family's desire for you to get married.
It is known of what is widespread in that country in which you live in in terms of wanton display, uncontrolled freedoms, and temptations that lead to falling into Fitnah (haraam things), and the scholars have mentioned that marriage is obligatory for those who fear for themselves falling into Fitnah.
The fear of the possible corruption of the child is not a valid justification for not getting married and missing out the interests and benefits that result from marriage, and the possibility of the child’s corruption exists even if a person marries in a Muslim country. The way to safeguard from this is by adopting legitimate reasons, of which the most important are seeking refuge with Allah the Almighty, following the example of the prophets, then choosing a good wife, and striving in the matter of proper education. You may find successful models in this aspect in the society in which you live in, so our advice to you is to get married, and if you are blessed with children, strive to properly raise them and seek the help of Allah the Almighty in that. Moreover, utilize the possible means of supplication and good advice, and find for them the right environment that may help in that, and it would be even better if you could migrate to a Muslim country.
Allah knows best.
