[Machine] He heard Talhah ibn Ubayd Allah say that a man came to the Messenger of Allah ﷺ and asked about Islam. The Messenger of Allah ﷺ replied, "There are five daily prayers during the day and night." The man asked if there was anything else besides them. The Messenger of Allah ﷺ replied, "No, unless you voluntarily offer extra prayers." This is narrated in Sahih al-Bukhari and Sahih Muslim in a hadith from Malik.
أَنَّهُ سَمِعَ طَلْحَةَ بْنَ عُبَيْدِ اللهِ يَقُولُ جَاءَ رَجُلٌ إِلَى رَسُولِ اللهِ ﷺ فَإِذَا هُوَ يَسْأَلُ عَنِ الْإِسْلَامِ فَقَالَ رَسُولُ اللهِ ﷺ خَمْسُ صَلَوَاتٍ فِي الْيَوْمِ وَاللَّيْلَةِ فَقَالَ هَلْ عَلَيَّ غَيْرُهَا قَالَ لَا إِلَّا أَنْ تَطَوَّعَ مُخَرَّجٌ فِي الصَّحِيحَيْنِ مِنْ حَدِيثِ مَالِكٍ
