A bedouin came to the Prophet (ﷺ) and said: "O Messenger of Allah! Direct me to a deed by which I may be entitled to enter Jannah." The Prophet (ﷺ) said, "Worship Allah, and never associate anything with Him, establish Salat, pay the Zakat which has been enjoined upon you, and observe Saum of Ramadan." He (the bedouin) said: "By Him in Whose Hand my soul is, I will never add anything to these (obligations)." When he turned his back, the Prophet (ﷺ) said, "He who wants to see a man from the dwellers of Jannah, let him look at him (bedouin)."
