The English language is used commonly in the world, that's why it's important to be learnt. Most universities use the English language to teach courses, and a lot of companies use it in their work, especially in documentation. When one wants to study books, especially scientific books, he needs to know English language, because most of the books are written in English. Also we need to learn it to protect ourselves against the evil of others, because the messenger of Allah, Mohammed, said 'Anyone who learns the language of others protects himself against their evils.'
