أَخْبَرَنَا مُحَمَّدُ بْنُ سَلَمَةَ، ‏‏‏‏‏‏قَالَ:‏‏‏‏ حَدَّثَنَا ابْنُ الْقَاسِمِ، ‏‏‏‏‏‏عَنْ مَالِكٍ، ‏‏‏‏‏‏قَالَ:‏‏‏‏ حَدَّثَنِي أَبُو سُهَيْلٍ، ‏‏‏‏‏‏عَنْ أَبِيهِ،‏‏‏‏ أَنَّهُ سَمِعَ طَلْحَةَ بْنَ عُبَيْدِ اللَّهِ، ‏‏‏‏‏‏يَقُولُ:‏‏‏‏ جَاءَ رَجُلٌ إِلَى رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ مِنْ أَهْلِ نَجْدٍ ثَائِرَ الرَّأْسِ،‏‏‏‏ يُسْمَعُ دَوِيُّ صَوْتِهِ،‏‏‏‏ وَلَا يُفْهَمُ مَا يَقُولُ حَتَّى دَنَا،‏‏‏‏ فَإِذَا هُوَ يَسْأَلُ عَنِ الْإِسْلَامِ ؟ قَالَ لَهُ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ:‏‏‏‏ خَمْسُ صَلَوَاتٍ فِي الْيَوْمِ وَاللَّيْلَةِ ، ‏‏‏‏‏‏قَالَ:‏‏‏‏ هَلْ عَلَيَّ غَيْرُهُنَّ ؟ قَالَ:‏‏‏‏ لَا،‏‏‏‏ إِلَّا أَنْ تَطَوَّعَ ، ‏‏‏‏‏‏قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ:‏‏‏‏ وَصِيَامُ شَهْرِ رَمَضَانَ ، ‏‏‏‏‏‏قَالَ:‏‏‏‏ هَلْ عَلَيَّ غَيْرُهُ ؟ قَالَ:‏‏‏‏ لَا،‏‏‏‏ إِلَّا أَنْ تَطَوَّعَ ، ‏‏‏‏‏‏وَذَكَرَ لَهُ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ الزَّكَاةَ، ‏‏‏‏‏‏فَقَالَ:‏‏‏‏ هَلْ عَلَيَّ غَيْرُهَا ؟ قَالَ:‏‏‏‏ لَا،‏‏‏‏ إِلَّا أَنْ تَطَوَّعَ ، ‏‏‏‏‏‏فَأَدْبَرَ الرَّجُلُ وَهُوَ، ‏‏‏‏‏‏يَقُولُ:‏‏‏‏ لَا أَزِيدُ عَلَى هَذَا وَلَا أَنْقُصُ مِنْهُ، ‏‏‏‏‏‏فَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ:‏‏‏‏ أَفْلَحَ إِنْ صَدَقَ .

Abu Suhail narrated from his father,: That he heard Talhah bin 'Ubaidullah say: A man from Najd with unkempt hair came to the Messenger of Allah [SAW]; he was speaking loudly but his speech could not be understood until he came close. He was asking about Islam. The Messenger of Allah [SAW] said: 'Five prayers every day and night.' He said: 'Do I have to do any more than that? He said: 'No, not unless you do it voluntarily.' The Messenger of Allah [SAW] said: 'Fasting the month of Ramadan.' He said: 'Do I have to do any more than that?' He said: 'No, not unless you do it voluntarily.' Then the Messenger of Allah [SAW] told him about Zakah. He said: 'Do I have to do any more than that?' He said: 'No, not unless you do it voluntarily.' The man left saying, 'I will not do any more than that or any less.' The Messenger of Allah [SAW] said: 'He will succeed, if he is telling the truth.'
