Abu Hurairah (May Allah be pleased with him) reported:
The Prophet (ﷺ) was asked: "Which deed is the best?" He (ﷺ) replied, "Faith in Allah and His Messenger." Then he was asked: "What is next?" He replied, "Jihad (holy fighting) in the Cause of Allah." Then he was asked, "What is after that?" He (ﷺ) replied, "Hajj Mabrur (an accepted pilgrimage)."[Al-Bukhari and Muslim].
