Ṣaḥīḥ Muslim
صَحِيحُ مُسْلِم
Considered one of the two most authentic collections of aḥādīth, second only to Bukhārī. It is unclear whether the author assigned a name to this book and it is commonly known as Ṣaḥīḥ Muslim (صحيح مسلم) (The Authentic Collection by Muslim). Sources: sunnah.com for the Arabic text and English translation. The English translation has been improved by myself and other contributors.
