What is the meaning and implication of verse 51 of Surah al-Maida?
"O you who have faith! Do not take the Jews and the Christians for allies: they are allies of each other. Any of you who allies with them is indeed one of them. Indeed Allah does not guide the wrongdoing lot." Qur'an 5:51
This verse is very clear the believers in the whole message of Islam should not associate nor be allies with those who don't believe in Islam despite the common things between us and them, but we are not allowed to be allies with them because of the ideological differences between us and them. We are not allowed to follow their aims which are usually based on their faith which is different from our faith in Islam.
Any Muslim who follows them will be like them.
Wassalam.
