Mishkat al-Masabih

Mu‘adh b. Jabal reported: I said, “Inform me, messenger of God, of an act which will cause me to enter paradise and remove me far from hell.” He replied, “You have asked a serious question, but it is easy for the one whom God helps to answer it. Worship God, associate nothing with Him, observe the prayer, pay the zakat, fast during Ramadan, and make the Pilgrimage to the House.” He said, “Shall I not guide you to the gateways of what is good? Fasting is a protection, and almsgiving extinguishes sin as water extinguishes fire, and a man's prayer in the middle of the night [has the same effect].” Then he recited, “Withdrawing themselves from their couches ... they have been doing.” 1 Then he said, “Shall I not guide you to the head and support of the matter and the top of its hump?” I replied, “Yes, messenger of God.” He said, “The head of the matter is Islam, its support is prayer, and the top of its hump is jihad.” Then he said, “Shall I not inform you of the controlling of all that?” I replied, “Yes, Prophet of God.” So he took hold of his tongue and said, “Restrain this.” I asked, “Prophet of God, shall we really be punished for what we talk about?” He replied, “I am surprised at you, 2 Mu'adh! Will anything but the harvests of their tongues overthrow men in hell on their faces (or, on their nostrils)?” Ahmad, Tirmidhi and Ibn Majah transmitted it.
