Sahih Muslim Book - 1, Hadith - 102

حَدَّثَنِي عَمْرُو بْنُ مُحَمَّدِ بْنِ بُكَيْرٍ النَّاقِدُ حَدَّثَنَا هَاشِمُ بْنُ الْقَاسِمِ أَبُو النَّضْرِ حَدَّثَنَا سُلَيْمَانُ بْنُ الْمُغِيرَةِ عَنْ ثَابِتٍ عَنْ أَنَسِ بْنِ مَالِكٍ قَالَ نُهِينَا أَنْ نَسْأَلَ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ عَنْ شَيْءٍ فَكَانَ يُعْجِبُنَا أَنْ يَجِيءَ الرَّجُلُ مِنْ أَهْلِ الْبَادِيَةِ الْعَاقِلُ فَيَسْأَلَهُ وَنَحْنُ نَسْمَعُ فَجَاءَ رَجُلٌ مِنْ أَهْلِ الْبَادِيَةِ فَقَالَ يَا مُحَمَّدُ أَتَانَا رَسُولُكَ فَزَعَمَ لَنَا أَنَّكَ تَزْعُمُ أَنَّ اللَّهَ أَرْسَلَكَ؟ قَالَ صَدَقَ قَالَ فَمَنْ خَلَقَ السَّمَاءَ؟ قَالَ: اللَّهُ قَالَ فَمَنْ خَلَقَ الْأَرْضَ؟ قَالَ: اللَّهُ قَالَ فَمَنْ نَصَبَ هَذِهِ الْجِبَالَ وَجَعَلَ فِيهَا مَا جَعَلَ قَالَ: اللَّهُ قَالَ فَبِالَّذِي خَلَقَ السَّمَاءَ وَخَلَقَ الْأَرْضَ وَنَصَبَ هَذِهِ الْجِبَالَ آللَّهُ أَرْسَلَكَ؟ قَالَ نَعَمْ قَالَ وَزَعَمَ رَسُولُكَ أَنَّ عَلَيْنَا خَمْسَ صَلَوَاتٍ فِي يَوْمِنَا وَلَيْلَتِنَا قَالَ صَدَقَ قَالَ فَبِالَّذِي أَرْسَلَكَ آللَّهُ أَمَرَكَ بِهَذَا؟ قَالَ نَعَمْ قَالَ وَزَعَمَ رَسُولُكَ أَنَّ عَلَيْنَا زَكَاةً فِي أَمْوَالِنَا قَالَ صَدَقَ قَالَ فَبِالَّذِي أَرْسَلَكَ آللَّهُ أَمَرَكَ بِهَذَا؟ قَالَ نَعَمْ قَالَ وَزَعَمَ رَسُولُكَ أَنَّ عَلَيْنَا صَوْمَ شَهْرِ رَمَضَانَ فِي سَنَتِنَا. قَالَ صَدَقَ قَالَ فَبِالَّذِي أَرْسَلَكَ آللَّهُ أَمَرَكَ بِهَذَا؟ قَالَ نَعَمْ قَالَ وَزَعَمَ رَسُولُكَ أَنَّ عَلَيْنَا حَجَّ الْبَيْتِ مَنْ اسْتَطَاعَ إِلَيْهِ سَبِيلًا قَالَ صَدَقَ قَالَ ثُمَّ وَلَّى قَالَ وَالَّذِي بَعَثَكَ بِالْحَقِّ! لَا أَزِيدُ عَلَيْهِنَّ وَلَا أَنْقُصُ مِنْهُنَّ فَقَالَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ لَئِنْ صَدَقَ لَيَدْخُلَنَّ الْجَنَّةَ.

It was narrated that Anas bin Malik said: "We were forbidden to ask the Messenger of Allah (s.a.w) about anything (needlessly), so it pleased us when a man came from the desert people and said: 'O Muhammad, your messenger has come to us telling us that you claim that Allah has sent you.' the Messenger of Allah (s.a.w) said: 'He spoke the truth.' He said: 'Who created the heavens?' He said: 'Allah.' He said: 'Who created the earth?' He said: 'Allah.' He said: 'Who raised these mountains and created whatever there is in them?' He said: 'Allah.' He said: 'By the One Who created the heavens and created the earth, and raised up these mountains, has Allah sent you?' The Messenger of Allah (s.a.w) said: 'Yes.' He said: Your messenger claimed that we have to offer five prayers each day and night.' The Messenger of Allah (s.a.w) said: 'He spoke the truth.' He said: 'By the One Who has sent you, is it Allah Who enjoined that upon you?' He said: 'Yes.' He said: 'Your messenger claimed that we must give Zakat from our wealth.' The Messenger of Allah (s.a.w) said: 'He spoke the truth.' He said: 'By the One Who has sent you, is it Allah Who enjoined that upon you?' He said: 'Yes.' He said: 'Your messenger claimed that we must fast the month of Ramadan each year.' The Messenger of Allah (s.a.w) said: 'He spoke the truth.' He said: 'By the One Who has sent you, is it Allah Who enjoined that upon you?' He said: 'Yes.' He said: 'Your messenger claimed that we must perform pilgrimage to the House, whoever is able to bear the journey.' The Messenger of Allah (s.a.w) said: 'He spoke the truth.' He turned to leave, then he said: 'By the One Who has sent you with the truth, I shall not do more than this or less.' The Prophet (s.a.w) said: 'If he is speaking the truth, he will enter Paradise.'"
