Specifying the Book with Ijma'a al-Sahaba
Bismillah al-Rahman al-Raheem
Specifying the Book with Ijma'a al-SahabaIjma'a al-Sahaba reveals a Shari’ah evidence. If the Sahaba establish a consensus stipulating that a certain rule is a Shari’ah rule, this means that they have evidence for this: they merely reported the rule but did not report the evidence. Thus, their consensus amounts to reporting the evidence. Consequently, their Ijma'a reveals the existence of a Shari’ah evidence; i.e. it reveals that they either heard the Messenger of Allah (saw) saying it, or saw him doing it or keeping silent over it. Hence, it is part of the Sunnah and it should be treated as such; also, the report must be accepted.
Since this is the case, it is therefore permitted to specify (make Takhsees) the Book with Ijma'a al-Sahaba. In fact, the specification i.e. al-Takhsees of the Qur’an with Ijma'a al-Sahaba did indeed occur. Allah (swt) says regarding the al-Qathifeen libellers: “And those who launch a charge against chaste women, and produce not four witnesses (to support their allegations), flog them with eighty stripes.” [24-4]. This rule was specified with Ijma'a al-Sahaba as applicable to freemen only and established the consensus that the penalty imposed on libelling slaves should be halved to forty lashes. The mere occurrence of this specification acts as evidence that it is permitted to specify the Book with Ijma'a al-Sahaba.
