Reviewing hadith together

Abu Nadrah said that Sayyiduna Abu Sa'id (may Allah be pleased with him) said: "Narrate hadith to one another, for it is hadith that stirs up hadith."

Abdullah bin Buraydah said that Sayyiduna Ali (may Allah be pleased with him) said: "Visit one another, and discuss hadith together. If you do not do so, hadith will fade away."

Ikrimah said: "Discuss hadith together, for discussing it is what keeps it alive."

Al-A'mash said that Isma'il bin Raja used to come to the boys who were learning to write and present his hadiths to them, so that he would not forget them.

Isa bin al-Musayyab said: I heard Ibrahim say: "When you hear a hadith, narrate it at the time you hear it, even if you narrate it to someone who has no desire for it, for it will then be preserved in your breast like a book."

Yazid said that Abd al-Rahman bin Abi Layla said: "The survival of the knowledge of hadith lies in discussing it." At this, Abdullah bin Shaddad said to him: "How many hadiths there are that you have kept alive in my breast!"

Al-A'mash said that the Messenger of Allah (peace and blessings be upon him) said: "The bane of knowledge is forgetting, and wasting knowledge is narrating it to those unworthy of it."

Al-Qasim said that Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) said: "The bane of knowledge is forgetting."
