There are four conditions in our school which must be fulfilled.

2) The second is that it has a clear-cut authenticity.
3) The third is that the meaning has to be clear.
4) It has to be agreed as being tawatur.
By Tawatur/Mutawattir. That is to say, mass transmitted in practice without additions, accretions or innovations. Alternatively, mass transmitted by disassociated chains of transmission such that it is not possible for them to have conspired upon a falsehood.
