[Machine] He said: O Messenger of Allah, inform me of an action that will enter its doer into Paradise. He replied: "How excellent, how excellent! Indeed, you have asked about something great, yet it is easy for the one who Allah makes it easy for. Worship Allah alone, without associating partners with Him, establish the obligatory prayers, give the obligatory charity, fast in Ramadan, and perform Hajj to the House. And shall I not inform you of the pillar of all this? Its top, its cornerstone, and its peak?" He said: "Yes, O Messenger of Allah." The Prophet ﷺ then said: "The pillar of all this is testifying that none has the right to be worshipped but Allah alone, the top of it is Jihad in the cause of Allah, and the peak of it is the prayer at its proper time." Then he said: "Shall I not inform you of the doors of goodness? Fasting is a shield, charity extinguishes sins as water extinguishes fire, and the standing of a person in prayer during the night." Then the Messenger of Allah ﷺ recited the verse: {Their sides draw away from their beds to invoke their Lord in fear and hope. And they spend (in Allah's Cause) out of what We have bestowed on them} [Quran 32:16]. Then he said: "Shall I not tell you of the controlling factor of all that?" He shook his own tongue and said: "Restrain this." Mu'adh said: "O Messenger of Allah, will we really be held accountable for what we say with our tongues?" He ﷺ said: "May your mother lose you, O Mu'adh! People will be thrown into the Hellfire only on their faces - or he said, on their noses - because of the harvests of their tongues."
