Sunan al-Nasa'i (Nasa'i's Hadith Collection)

Sunan al-Nasa'i is one of the six canonical hadith collections in Sunni Islam. It was compiled by Imam Abu Abd al-Rahman Ahmad ibn Shu'ayb al-Nasa'i (829-915 CE) and is considered to have the strictest authenticity criteria after Sahih al-Bukhari and Sahih Muslim.

Al-Nasa'i first wrote "al-Sunan al-Kubra" (The Large Sunan) and then distilled it into "al-Sunan al-Sughra" (The Small Sunan), also called "al-Mujtaba," which is the version included among the six canonical collections. The work contains approximately 5,761 hadith organized into 51 books.

Imam al-Nasa'i's chapter on prayer is particularly detailed and covers meticulous aspects of prayer practice. He includes narrations about the precise manner of raising the hands (raf' al-yadayn), the placement of fingers during tashahhud, and the specific supplications the Prophet (peace be upon him) recited in different parts of the prayer.
