Sunan Abi Dawud Book 15, Hadith 10
A man said: Messenger of Allah, allow tourism for me. The Prophet (ﷺ) said: The tourism of my people is striving in the path of Allah, the Exalted.
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.””
The Prophet (ﷺ) said: Returning home is like going on an expedition.
