question #3 Sahih Muslim 945f, Book 11, Hadith 71 : What can be learned from the practice of seeking confirmation from knowledgeable individuals in religious matters?

He who follows the bier, for him is the reward of one qirat. Ibn ‘Umar said: Abu Huraira narrated it too often. So he sent (a messenger to) ‘A’isha to ascertain (the fact). She (‘A’isha) testified Abu Huraira. Ibn ‘Umar said: We missed so many qirats.
