"We were forbidden in the Quran to ask the Prophet about anything not imperative, so we liked it when a wise man from among the people of the desert came and asked him. A man from among the desert people came and said: 'O Muhammad, your messenger came to us and told us that you say that Allah, the Mighty and Sublime, has sent you.' He 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 set up the mountains in it?' He said: 'Allah.' He said: 'Who created beneficial things in them?' He said: 'Allah.' He said: 'By the One Who created the heavens and the Earth, and set up the mountains therein, and created beneficial things in them, has Allah sent you?' He said: 'Yes.' He said: 'Your messenger said that we have to offer five prayers each day and night.' He said: 'He spoke the truth.' He said: 'By the One Who sent you, has Allah commanded you to do this?' He said: 'Yes.' He said: 'Your messenger said that we have to pay Zakah on our wealth.' He said: 'He spoke the truth.' He said: 'By the One Who sent you, has Allah commanded you to do this?' He said: 'Yes.' He said: 'Your messenger said that we have to fast the month of Ramadan each year.' He said: 'He spoke the truth.' He said: 'By the One Who sent You, has Allah commanded you to do this?' He said: 'Yes.' He said: 'Your messenger said that we have to perform Hajj, those who can afford it.' He said: 'He spoke the truth.' He said: 'By the One Who sent you, has Allah commanded you to do this?' He said: 'Yes.' He said: 'By the One Who sent you with the truth, I will not do more than this or less.' When he left, the Prophet said: 'If he is sincere, he will certainly enter paradise.'" (Using translation from Nasāʾī 2091)  

أَنْ نَسْأَلَ النَّبِيَّ ﷺ عَنْ شَيْءٍ فَكَانَ يُعْجِبُنَا أَنْ يَجِيءَ الرَّجُلُ الْعَاقِلُ مِنْ أَهْلِ الْبَادِيَةِ فَيَسْأَلَهُ فَجَاءَ رَجُلٌ مِنْ أَهْلِ الْبَادِيَةِ فَقَالَ يَا مُحَمَّدُ أَتَانَا رَسُولُكَ فَأَخْبَرَنَا أَنَّكُ تَزْعُمُ أَنَّ اللهَ أَرْسَلَكَ قَالَ «صَدَقَ» قَالَ فَمَنْ خَلَقَ السَّمَاءَ؟ قَالَ «اللهُ» قَالَ فَمَنْ خَلَقَ الْأَرْضَ؟ قَالَ «اللهُ» قَالَ فَمَنْ نَصَبَ فِيهَا الْجِبَالَ؟ قَالَ «اللهُ» قَالَ فَمَنْ جَعَلَ فِيهَا الْمَنَافِعَ؟ قَالَ «اللهُ» قَالَ فَبِالَّذِي خَلَقَ السَّمَاءَ وَالْأَرْضَ وَنَصَبَ فِيهَا الْجِبَالَ وَجَعَلَ فِيهَا الْمَنَافِعَ آاللهُ أَرْسَلَكَ؟ قَالَ «نَعَمْ» قَالَ وَزَعَمَ رَسُولُكَ أَنَّ عَلَيْنَا خَمْسَ صَلَوَاتٍ فِي كُلِّ يَوْمٍ وَلَيْلَةٍ قَالَ «صَدَقَ» قَالَ فَبِالَّذِي أَرْسَلَكَ اللهُ 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 شَهْرٍ فِي كُلِّ سَنَةٍ قَالَ «صَدَقَ» قَالَ فَبِالَّذِي أَرْسَلَكَ آللَّهُ أَمَرَكَ بِهَذَا؟ قَالَ «نَعَمْ» قَالَ وَزَعَمَ رَسُولُكَ أَنَّ عَلَيْنَا الْحَجَّ مَنِ اسْتَطَاعَ إِلَيْهِ سَبِيلًا قَالَ «صَدَقَ» قَالَ فَبِالَّذِي أَرْسَلَكَ آللَّهُ أَمَرَكَ بِهَذَا؟ قَالَ «نَعَمْ» قَالَ وَالَّذِي بَعَثَكَ بِالْحَقِّ لَا أَزِيدُ عَلَيْهِنَّ وَلَا أَنْقُصُ فَلَمَّا وَلَّى قَالَ النَّبِيُّ ﷺ «لَئِنْ صَدَقَ لَيَدْخُلَنَّ الْجَنَّةَ»
