Shaykh Muhammad Nasir ud-Deen Al-Albaanee about Voting:
Question: What is the ruling on some of the American Muslims participating in the elections that take place in America? They use as proof for that the principle of taking the lesser of two evils. They think that one of those candidates who are running for office will be less oppressive & less problematic upon Islam & the Muslims?
Answer: Kufr is one religion & [our] Rabb Azza wa Jal reminds those Muslims who think they are applying the principle of taking the lesser of two evils; Allaah Ta ‘Ala said, “And never will the Jews or the Christians be pleased with you until you follow their religion” (Al-Qur’an: 2: 120).
So I am amazed with all amazement at these youth who rely upon the likes of this delusion as occurs in your question, Barak Allaah feek. And Allaah Azza wa Jal says, “And don’t incline towards those who do wrong such that the fire should touch you…” (Al-Qur’an: 11: 113). And the fire of the dunya (worldly life) comes before the fire of the Hereafter.
Due to that we say that it is not permissible to participate in the likes of these elections because that participation means taking the Kuffar (disbelievers) as friends through your actions. And that is Haraam (impermissible) according to the text of the Qur’an, where the Rabb ul-Anaam said, “And if any amongst you take them as friends then he is surely one of them.” (Al-Qur’an 5: 51).
