حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدِ بْنِ جَمِيلِ بْنِ طَرِيفِ بْنِ عَبْدِ اللَّهِ الثَّقَفِيُّ، عَنْ مَالِكِ بْنِ أَنَسٍ، - فِيمَا قُرِئَ عَلَيْهِ - عَنْ أَبِي سُهَيْلٍ، عَنْ أَبِيهِ، أَنَّهُ سَمِعَ طَلْحَةَ بْنَ عُبَيْدِ اللَّهِ، يَقُولُ جَاءَ رَجُلٌ إِلَى رَسُولِ اللَّهِ صلى الله عليه وسلم مِنْ أَهْلِ نَجْدٍ ثَائِرُ الرَّأْسِ نَسْمَعُ دَوِيَّ صَوْتِهِ وَلاَ نَفْقَهُ مَا يَقُولُ حَتَّى دَنَا مِنْ رَسُولِ اللَّهِ صلى الله عليه وسلم فَإِذَا هُوَ يَسْأَلُ عَنِ الإِسْلاَمِ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " خَمْسُ صَلَوَاتٍ فِي الْيَوْمِ وَاللَّيْلَةِ " . فَقَالَ هَلْ عَلَىَّ غَيْرُهُنَّ قَالَ " لاَ . إِلاَّ أَنْ تَطَّوَّعَ وَصِيَامُ شَهْرِ رَمَضَانَ " . فَقَالَ هَلْ عَلَىَّ غَيْرُهُ فَقَالَ " لاَ . إِلاَّ أَنْ تَطَّوَّعَ " . وَذَكَرَ لَهُ رَسُولُ اللَّهِ صلى الله عليه وسلم الزَّكَاةَ فَقَالَ هَلْ عَلَىَّ غَيْرُهَا قَالَ " لاَ . إِلاَّ أَنْ تَطَّوَّعَ " قَالَ فَأَدْبَرَ الرَّجُلُ وَهُوَ يَقُولُ وَاللَّهِ لاَ أَزِيدُ عَلَى هَذَا وَلاَ أَنْقُصُ مِنْهُ . فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " أَفْلَحَ إِنْ صَدَقَ " .
Five prayers during the day and the night. (Upon this he said: Am I obliged to say any other (prayer) besides these? He (the Holy Prophet, ) said: No, but whatever you observe voluntarily, out of your own free will, and the fasts of Ramadan. The inquirer said: Am I obliged to do anything else besides this? He (the Holy Prophet) said: No, but whatever you do out of your own free will. And the Messenger of Allah told him about the Zakat (poor-rate). The inquirer said: Am I obliged to pay anything else besides this? He (the Holy Prophet) said: No, but whatever you pay voluntarily out of your own free will. The man turned back and was saying: I would neither make any addition to this, nor will decrease anything out of it. The Prophet remarked: He is successful, if he is true to what he affirms.
