حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مَسْلَمَةَ، عَنْ مَالِكٍ، عَنْ عَمِّهِ أَبِي سُهَيْلِ بْنِ مَالِكٍ، عَنْ أَبِيهِ، أَنَّهُ سَمِعَ طَلْحَةَ بْنَ عُبَيْدِ اللَّهِ، يَقُولُ جَاءَ رَجُلٌ إِلَى رَسُولِ اللَّهِ صلى الله عليه وسلم مِنْ أَهْلِ نَجْدٍ ثَائِرَ الرَّأْسِ يُسْمَعُ دَوِيُّ صَوْتِهِ وَلاَ يُفْقَهُ مَا يَقُولُ حَتَّى دَنَا فَإِذَا هُوَ يَسْأَلُ عَنِ الإِسْلاَمِ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏خَمْسُ صَلَوَاتٍ فِي الْيَوْمِ وَاللَّيْلَةِ ‏"‏ ‏.‏ قَالَ هَلْ عَلَىَّ غَيْرُهُنَّ قَالَ ‏"‏ لاَ إِلاَّ أَنْ تَطَّوَّعَ ‏"‏ ‏.‏ قَالَ وَذَكَرَ لَهُ رَسُولُ اللَّهِ صلى الله عليه وسلم صِيَامَ شَهْرِ رَمَضَانَ قَالَ هَلْ عَلَىَّ غَيْرُهُ قَالَ ‏"‏ لاَ إِلاَّ أَنْ تَطَّوَّعَ ‏"‏ ‏.‏ قَالَ وَذَكَرَ لَهُ رَسُولُ اللَّهِ صلى الله عليه وسلم الصَّدَقَةَ ‏.‏ قَالَ فَهَلْ عَلَىَّ غَيْرُهَا قَالَ ‏"‏ لاَ إِلاَّ أَنْ تَطَّوَّعَ ‏"‏ ‏.‏ فَأَدْبَرَ الرَّجُلُ وَهُوَ يَقُولُ وَاللَّهِ لاَ أَزِيدُ عَلَى هَذَا وَلاَ أَنْقُصُ ‏.‏ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ أَفْلَحَ إِنْ صَدَقَ ‏"‏ ‏.‏
Translation
Talhah b. 'Ubaid Allah said

A man came to the Messenger of Allah (ﷺ) from the people of Najd with disheveled hair; the humming sound of his voice could be heard, but what he was saying could not be understood until he drew near. Then, behold, he was asking about Islam. The Messenger of Allah (ﷺ) said, "Five prayers during the day and night." He asked, "Must I perform any other than them?" He replied, "No, unless you do so voluntarily." And the Messenger of Allah (ﷺ) mentioned to him the fasting of the month of Ramadan. He asked, "Must I observe any other?" He replied, "No, unless you do so voluntarily." And the Messenger of Allah (ﷺ) mentioned charity to him. He asked, "Must I give any other than it?" He replied, "No, unless you do so voluntarily." Then the man turned away, saying, "By Allah, I will neither add to this nor fall short of it." The Messenger of Allah (ﷺ) said, "He has succeeded if he has spoken the truth."
