HOW TO BE PROSPEROUS H 1230 "A man from Najd with disheveled hair came to the Messenger of Allah, praise and peace be upon him. His voice reached our ears but we could not understand what he was saying until he drew nearer to the Messenger of Allah, praise and peace be upon him, and then we understood that he was inquiring about Islam. The Messenger of Allah, praise and peace be upon him, told him, 'There are five obligatory prayers during the day and night. He asked, 'Is there more than that?' The Messenger of Allah, praise and peace be upon him, replied, 'No, unless you wish to offer voluntary prayers. Then fasting during the month of Ramadan.' The man asked, 'Is there more than that?' The Messenger of Allah, praise and peace be upon him, replied, 'No, unless you wish to observe voluntary fasting.' Then the Messenger of Allah, praise and peace be upon him, told him about the payment of the obligatory charity (zakat) and the man asked the same question again and the Messenger of Allah, praise and peace be upon him, replied in the same way. Then the man turned away saying, 'As Allah is my witness, I shall not add anything to this, nor shall I detract anything from it.' Upon this the Messenger of Allah, praise and peace be upon him, said, 'He will prosper if he is truthful.'" R 1230 Bukhari and Muslim with a chain up to Talha the son of Ubaidullah who related that the Messenger of Allah, praise and peace be upon him, said this.
1207- وعن طَلْحَةَ بن عبيد الله رضي الله عنه ، قَالَ : جَاءَ رَجُلٌ إِلَى رسولِ الله صلى الله عليه وآله وسلم مِنْ أَهْلِ نَجْدٍ ثَائِرُ الرَّأسِ نَسْمَعُ دَوِيَّ صَوْتِهِ ، وَلاَ نَفْقَهُ مَا يَقُولُ ، حَتَّى دَنَا مِنْ رسولِ الله صلى الله عليه وآله وسلم ، فَإذا هُوَ يَسألُ عَنِ الإسْلاَم ، فَقَالَ رسول الله صلى الله عليه وآله وسلم : "خَمْسُ صَلَواتٍ في اليَوْمِ وَاللَّيْلَةِ" قَالَ : هَلْ عَلَيَّ غَيْرُهُنَّ ؟ قَالَ : "لاَ ، إِلاَّ أنْ تَطَّوَّعَ" فَقَالَ رسولُ الله صلى الله عليه وآله وسلم : "وَصِيامُ شَهْرِ رَمَضَانَ" قَالَ : هَلْ عَلَيَّ غَيْرُهُ ؟ قَالَ : "لاَ ، إِلاَّ أنْ تَطَّوَّعَ" قَالَ : وَذَكَرَ لَهُ رسول الله صلى الله عليه وآله وسلم الزَّكَاةَ ، فَقَالَ : هَلْ عَلَيَّ غَيْرُهَا ؟ قَالَ : "لاَ ، إِلاَّ أنْ تَطَّوَّعَ" فَأدْبَرَ الرَّجُلُ وَهُوَ يَقُولُ : وَاللهِ لاَ أُزِيدُ عَلَى هَذَا وَلاَ أنْقُصُ مِنْهُ ، فَقَالَ رسول الله صلى الله عليه وآله وسلم : "أفْلَحَ إنْ صَدَقَ" متفقٌ عَلَيْهِ .
