Is the compilation of transmission chains a strong argument for the improvement of a Hadith, despite many scholars weakening it? And what are the conditions for improving a Hadith through the compilation of transmission chains? And was Sheikh Al-Albani unique in these conditions? And can a weak Hadith be elevated to the rank of Sahih through the compilation of transmission chains?

The reasons for criticizing narrators are of two types: The first is what compromises a narrator's 'adala (uprightness), such as lying or committing major sins (fisq). This type of weakness is not removed by a multiplicity of chains of narration. As for the second type, it compromises a narrator's memorization, precision, and connection (ittisal), such as heedlessness (ghaflah) or poor memory (su' al-hifz). This type of weakness is removed by a multiplicity of chains and sources, whereby the hadith is strengthened and elevated to the rank of hasan li-ghayrihi (good due to external factors) or sahih (authentic). An example of this is the case of 'Abdullah ibn Lahi'ah, whose errors became frequent after his books were burned, yet the majority of his narrations are sound. This is what scholars call i'tibar (consideration) and i'tidal (mutual strengthening). This detailed explanation is found in books of mustalah al-hadith (hadith terminology) under the chapter of hadith hasan or hadith da'if.
