Narrated Abu Hurairah:

"The Messenger of Allah (ﷺ) was asked: 'Which deed is the most virtuos ? And which deed is the best ?' He (ﷺ) said: 'Faith in Allah and His Messenger.' It was said: 'Then what ?' He said: 'Jihad is the hump (the most prominent) of the deeds.' Then what O Messenger of Allah ? He said: 'Then Hajj Mabrur.'"

[Abu 'Eisa said:] This Hadith is Hasan Sahih, it has been reported through other routes from Abu Hurairah from the Prophet (ﷺ).
