Sunan An-Nasa'i (6 Vol. Set)

Imam Hafiz Abu Abdur Rahman Ahmad bin Shu'aib bin 'Ali An-Nasa'e (309AH / 915CE) compiled Sunan An-Nasai which has the fewest weak ahadith after the two sahih collections. The sunan which is one of the six is al Mujtaba or as Sunan as Sughara, which is a synopsis of a large collection of hadiths which he considered to be fairly reliable. In the smaller collection he only included those hadiths which he considered to be reliable.
