Changing the name and attributing the children to others to facilitate entering a foreign country

Q: As the following question is being posed by many people, I have thought it may be a good idea to send it to Your Eminence to give us a detailed answer In Sha’a-Allah (if Allah wills).The British Government has banned foreigners from entering Britain to reside there, except for those whose parents are residents in the UK. Therefore, some Muslims make a trick (Part No. 20; Page No. 384) and change their lineage to be able to enter Britain. They attribute to themselves children who are not theirs. For example, a person claims his brother is his son, or his nephew is his own son, and so on. I would like to pose the following questions: a) What is the ruling of Shari`ah (Islamic law) on changing one's lineage? B) Is it permissible for someone who has already entered Britain through the way mentioned above to remain there or should they leave even after a period of time? It may be worth mentioning that some people have already entered Britain through the way mentioned above some years ago and have bought houses and some other possessions there.I hope Your Eminence would answer my question as soon as possible.

A: It is not permissible to change one's lineage even for the reason which is mentioned in the question. In fact, doing so is Haram (prohibited) and is considered a major sin, because it involves lying and falsehood and it opposes Allah's Purified Shar` (Law) which commands Muslims to preserve lineages. Therefore, it is Wajib (obligatory) for whoever has indulged in such a sin to make Tawbah (repentance to Allah), hasten to correct their names immediately, and leave the non-Muslim country to live in a Muslim one to be able to perform the obligatory acts of worship properly. By doing so, they will increase the number of Muslims, cooperate with them in acts of righteousness and piety, and protect themselves from Fitnah (temptation). (Part No. 20; Page No. 385) May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
