Sunan Abi Dawud Book 15, Hadith 8
The Prophet (ﷺ) said: A section of my community will continue to fight for the right and overcome their opponents till the last of them fights with the Antichrist.
The Prophet (ﷺ) said: It will turn out that you will be armed troops, one is Syria, one in the Yemen and one in Iraq. Ibn Hawalah said: Choose for me, Messenger of Allah, if I reach that time. He replied: Go to Syria, for it is Allah's chosen land, to which his best servants will be gathered, but if you are unwilling, go to your Yemen, and draw water from your tanks, for Allah has on my account taken special charge of Syria and its people.
Abu Sa’id (Al Khudri) reported The Prophet(ﷺ) was asked “Which believers are most perfect in respect of faith? He replied “A man who strives in the path of Allaah with his life and property and a man who worships Allaah in a mountain valley where he protects the people from his evil.””
