This hadith has been narrated through another chain of transmitters.
The Book of Marriage - Sahih Muslim 1419b
This narration, transmitted through an alternate chain of narrators (isnad), serves to strengthen the authenticity of the preceding hadith. In the science of hadith, multiple chains of transmission for the same text indicate greater reliability and widespread acceptance among the Companions.
The scholars of hadith consider such parallel transmissions as evidence that the Prophet's teaching was widely disseminated and preserved through various reliable sources, thereby eliminating doubt about its authenticity and ensuring its preservation from potential errors in any single chain.
Scholarly Commentary
Al-Nawawi, in his commentary on Sahih Muslim, explains that when a hadith is transmitted through multiple chains, it demonstrates the care with which the Muslim community preserved the Sunnah. Each chain serves as independent verification of the others.
Ibn Hajar al-Asqalani notes in Fath al-Bari that parallel transmissions strengthen the hadith's classification and help identify any subtle variations in wording that might clarify the intended meaning, while confirming the core message remains consistent across all transmissions.
