I accompanied the Prophet ﷺ on a journey. One day I was near him while we were moving so I said: "O Messenger of Allah! Inform me about an action by which I will be admitted into Paradise, and which will keep me far from the Fire." He said: "You have asked me about something great, but it is easy for whomever Allah makes it easy: (1) Worship Allah and do not associate any partners with Him, (2) establish the Salah, (3) give the Zakat, (4) fast Ramadan and, (5) perform Hajj to the House.'
Then he ﷺ said: "Shall I not guide you to the doors of good? (1) Fasting is a shield, and (2) charity extinguishes sins like water extinguishes fire, and (3) a person's prayer in depths of the night." Then he ﷺ recited: "Their sides forsake their beds to call upon their Lord..." until he reached "what they used to do." [Sajdah 32:16-17]
Then he ﷺ said: "Shall I not inform you about the head of the entire matter, and its pillar, and its hump?" I said: "Of course, O Messenger of Allah!" He ﷺ said: "The head of the matter is Islam, and its pillar is the Salah, and its hump is Jihad."
Then he ﷺ said: "Shall I not inform you about what governs all of that?" I said: "Of course, O Messenger of Allah!" So he ﷺ grabbed his tongue and he said: "Restrain this." I said: "O Prophet of Allah! Will we be taken to account for what we say?" He said: "May your mother grieve your loss O Muadh! Are the people not tossed into the Hellfire upon their faces," or "upon their noses, except because of what their tongues have wrought?"
كُنْتُ مَعَ النَّبِيِّ ﷺ فِي سَفَرٍ فَأَصْبَحْتُ يَوْمًا قَرِيبًا مِنْهُ وَنَحْنُ نَسِيرُ فَقُلْتُ يَا رَسُولَ اللَّهِ أَخْبِرْنِي بِعَمَلٍ يُدْخِلُنِي الْجَنَّةَ وَيُبَاعِدُنِي مِنَ النَّارِ قَالَ: «لَقَدْ سَأَلْتَنِي عَنْ عَظِيمٍ، وَإِنَّهُ لَيَسِيرٌ عَلَى مَنْ يَسَّرَهُ اللَّهُ عَلَيْهِ: (١) تَعْبُدُ اللَّهَ وَلاَ تُشْرِكُ بِهِ شَيْئًا، (٢) وَتُقِيمُ الصَّلاَةَ، (٣) وَتُؤْتِي الزَّكَاةَ، (٤) وَتَصُومُ رَمَضَانَ، (٥) وَتَحُجُّ الْبَيْتَ۔»
ثُمَّ قَالَ: «أَلاَ أَدُلُّكَ عَلَى أَبْوَابِ الْخَيْرِ؟ (١) الصَّوْمُ جُنَّةٌ، (٢) وَالصَّدَقَةُ تُطْفِئُ الْخَطِيئَةَ كَمَا يُطْفِئُ الْمَاءُ النَّارَ، (٣) وَصَلاَةُ الرَّجُلِ مِنْ جَوْفِ اللَّيْلِ۔» قَالَ ثُمَّ تَلاََ {تَتَجَافَى جُنُوبُهُمْ عَنِ الْمَضَاجِعِ} حَتَّى بَلَغَ {يَعْمَلُونَ} [السجدة 16-17]»
ثُمَّ قَالَ: «أَلاَ أُخْبِرُكَ بِرَأْسِ الأَمْرِ كُلِّهِ وَعَمُودِهِ وَذِرْوَةِ سَنَامِهِ؟» قُلْتُ: بَلَى يَا رَسُولَ اللَّهِ قَالَ: «رَأْسُ الأَمْرِ الإِسْلاَمُ وَعَمُودُهُ الصَّلاَةُ وَذِرْوَةُ سَنَامِهِ الْجِهَادُ۔»
ثُمَّ قَالَ: «أَلاَ أُخْبِرُكَ بِمَلاَكِ ذَلِكَ كُلِّهِ؟ قُلْتُ: بَلَى يَا نَبِيَّ اللَّهِ قَالَ فَأَخَذَ بِلِسَانِهِ قَالَ: «كُفَّ عَلَيْكَ هَذَا۔» فَقُلْتُ يَا نَبِيَّ اللَّهِ، وَإِنَّا لَمُؤَاخَذُونَ بِمَا نَتَكَلَّمُ بِهِ؟ فَقَالَ: «ثَكِلَتْكَ أُمُّكَ يَا مُعَاذُ، وَهَلْ يَكُبُّ النَّاسَ فِي النَّارِ عَلَى وُجُوهِهِمْ» أَوْ «عَلَى مَنَاخِرِهِمْ إِلاَّ حَصَائِدُ أَلْسِنَتِهِمْ؟»
