Shaykh Salih Ali-Shaykh said, “This is similar to the question (asking about making supplication for overall destruction for the Jews and Christians) that was asked when I visited al-Da’wah Publications that publishes “al-Da’wah” magazine.

I have mentioned many times in the past that doing such a thing (supplicatting for the overall destruction of all the Jews and Christians) is not in accordance with the fundamentals of our belief and creed.

The supplication for the overall destruction of nonbelievers was specific to prophet Nuh (Noah). The messengers after him did not pray inclusively for absolute destruction of all nonbelievers.

Allah said: And Nuh said, “My Lord, do not leave upon the earth a single one of the disbelievers.” [Surah Nuh, 71:26]

Yet, an angel said to prophet Muhammad (after being rejected and persecuted by his people), “If you want, I will crush the two mountains upon the people of Mecca.”

The prophet replied saying: No, I hope Allah will bring out from their progeny people who’ll worship Allah alone ascribing no partner to Him.” Recorded by al-Bukhari (no. 3231) and Muslim (1795) from the ḥadith of Aishah, may Allah be pleased with her.

The prophet also once condemned some of the foremost and harshest of the leaders of disbelief, so the following verse was revealed to him, as is mentioned in “Kitab al-Tawḥid”, Allah revealed: You have nothing to do with the decision, whether He pardons them or punishes them. Indeed, they are the transgressors. [Surah Ali-Imran, 3:128]

The guidance of the prophet and his companions regarding their supplications against nonbelievers is that they would only pray specifically against the transgressors and unjust among them, the oppressors, or those who openly wage war against Islam and its people.

This is also illustrated in the supplication of Umar when he was in prayer: “Oh Allah, deal with the disbelievers from the People of the Book that hinder others from Your religion and that fight Your righteous servants.”

As for praying against all Jews and Christians for their overall extermination, this is not permissible in Islam. It is a form of going to extremes in supplication. This is because Allah has already informed us that the Jews and Christians will remain until the appearance of the Anti-Christ (al-Masiḥ al-Dajjal) towards the end of time.

So, if someone prays to Allah for Him to remove all of them now before the Anti-Christ appears, then this is a contradiction and a form of objection to what Allah has already decreed with His wisdom and capability in that He will make them remain until the end of time.

For this, it has never been narrated from anyone of the Salaf, or from the major scholars of Islam that they supplicated with an overall prayer against the Jews and Christians. Instead, they would supplicate with a specific prayer only against those who fight, wage war, or harm the believers.”
