I was thinking I'll write up a practical example of how the Chain of Narration system works for Hadiths, because it'd be fun, and also a look into what makes Islam a religion that is supremely concerned about authenticity.
[hide]First, imagine we are all from a nation of people renowned for their memories, who have memorised their lineage up to 10, 20, 30 generations, and who have passed down poetry in verbal form, word for word, generation by generation. The following people in this example are ones who have the reputation to be truthful, competent, honest, free of bias, and have accurate memories.
**Femme says:
"I like cookies."**
Monkey King and RoboBlue were there and heard Femme say this directly.
Time passes and Monkey King and RoboBlue meet up with different people.
Monkey King says:
"I was going to the kitchen to get a can of whoopass and I heard Femme say she likes cookies."
Wolfwood and Lord Gaimon was there and witnessed Monkey King say that.
Roboblue says:
"I was waiting with Femme for the chicken to be done in the oven and I heard Femme say she likes cookies."
Firelord and Captain Ugly were there and witnessed Roboblue say that.
Time passes and those four meet up with different people.
Wolfwood says:
"I heard Monkey King say that he was in the kitchen to get a can of whoopass when he heard Femme say she likes cookies."
Xan was there and witnessed Wolfwood say that.
Lord Gaimon says:
"I heard Monkey King say that he was in the kitchen to get a can of whoopass when he heard Femme say she likes cookies."
Sggupta and Hosemisnuba were there and witnessed Lord Gaimon say that.

Firelord says:
"I heard Roboblue say that he was waiting with Femme for the chicken to be done in the oven when she said that she likes cookies."
Smokersan was there and witnessed Firelord say that.
Captain Ugly says:
"I heard Roboblue say that he was waiting with Femme for the chicken to be done in the oven when she said that she likes cookies."
MetaMario and Dr. Faust were there and witnessed Captain Ugly say that. Time passes and Robby, the collector of verbal accounts of Femme, talks to Xan, Sggupta, Hosemisnuba, Smokersan, MetaMario, and Dr. Faust.
Xan says:
I heard Wolfwood say that Monkey King said that he was in the kitchen for a can of whoopass when Femme said she liked cookies.
Sggupta says:
Hosemisnuba and I were playing smash when Lord Gaimon said that Monkey King said that he was in the kitchen for a can of whoopass when Femme said she liked cookies.
Hosemisnuba says:
Sggupta and I were playing smash when Lord Gaimon said that Monkey King said that he was in the kitchen for a can of whoopass when Femme said she liked cookies.
Smokersan says:
I was petting my cat when Firelord said that Roboblue said that he was waiting for Femme to be done with the chicken when she said that she liked cookies.
MetaMario says:
I was eating a sandwich with Dr. Faust when we heard Captain Ugly say that Roboblue said that he was waiting for Femme to be done with the chicken when she said that she liked cookies.
Dr. Faust says:
I was eating a sandwich with MetaMario when we heard Captain Ugly say that Roboblue said that he was waiting for Femme to be done with the chicken when she said that she liked cookies.
Robby has all the accounts of this verbal account of Femme. He creates four hadiths for four chains of confirmed authentic narrations:
1. Dr. Faust and Metamario said that Captain Ugly said that Roboblue said that Femme said that she likes cookies.
2. Smokersan said that Firelord said that Roboblue said that Femme said that she likes cookies.
3. Hosemisnuba and Sggupta said that Lord Gaimon said that Monkey King said that Femme said that she likes cookies.
4. Xan said that Wolfwood said that Monkey King said that Femme said that she likes cookies.

One instance, 12 people who have confirmed that Femme said she liked cookies, and since these 12 people are known to be reputable in transmitting other accounts of Femme that were true, then these four chains are confirmed to be the highest grade of authentic.[/hide]
That's basically how the Chain of Narration system works, but it's way more complicated than this, because each narrator's reputation for transmitting hadith (or verbal accounts of Muhammad) is closely scrutinized, and if one person in the chain is known to have a deficient memory, the authenticity of that hadith is weakened from saheeh (authentic) to hasan (good) to musnad (supported) to da'if (weak) to fabricated.
