Shaykh Saalih Ibn Fawzaan Al-Fawzaan (hafidhahullaah) stated:
“The actions, disbelief and evil of the Yahood (Jews) is well known, even (with regards) to (their relationship) with their Prophets. They killed their Prophets and (also) is that which occurred with Kaleemullaah – Moosaa (‘alayhis salaam), such as what Allah has related in the Qur`an (regarding) the story of Moosaa and Haaroon (‘alayhimas salaam).
The character, disbelief, misguidance and evil of the Yahood is well known – even towards their Prophets – but what is obligatory upon us (Muslims) is that we ponder and rectify our deviated affairs and repent to Allah because the Yahood have not gained the upper hand over us except due to our sins. Why is it that we do not hear anyone addressing and admonishing the Muslims whilst saying to them:
‘What has happened to you is (nothing else) but as a result of your turning away from the religion of Allah and negligence in the affairs of the Deen. So repent to Allah in order that Allah may aid you and avert the plot of the plotters from you.’
We do not hear except insult, abuse, and supplication against the Yahood, but this should be substituted with supplicating to Allah to rectify the Muslims and to make them steadfast. And to mention to the Muslims that they should repent and return to Allah, and rectify their Deen for the sake of Allah. This is the first obligation.
As for supplication against an oppressor – be it the Yahood or other than them – then there is nothing wrong with this. It is legislated to supplicate against the one who oppress you with the sharee’ah supplications, the supplications found in the Book and the Sunnah. But before supplicating against them, you should supplicate to Allah to rectify the Muslims and to make the Muslims steadfast upon their Religion and return them to the truth. (And) advise, address and admonish (them) with regards to (obedience to) Allah. This is what is obligatory.”

"How strange is an Ummah that doesn’t fight in jihād except that they are called khawārij?
How strange is an Ummah that doesn’t strive in applying the Shariah except they are called khawārij?
How strange is an ummah that doesn’t frighten it’s enemies except they are called khawārij?
How strange is an ummah that the khawārij smile at the time of death?”
