حكمه: وجوب الطلب حتى يزول عنه الخفاء.
Its ruling is that investigation must continue until the obscurity is removed.
Here talab does not mean collecting arbitrary opinions. It requires examining relevant usage, legally effective characteristics and applicable evidence so the particular case can be classified with justification.
For tarrar and nabbash, for example, one identifies the legally relevant elements of theft and then assesses whether the facts of the special case meet those elements. Mere confidence without investigation cannot substitute for the required inquiry.
