This article discusses weak hadith and its requirement for the use of rule
determination of Islamic law according to Shāfiʿī school. This current study
objectively provides the insights for Muslims in Malaysia relating to the methods
of weak hadith’s application by Shāfiʿī school. Therefore, Malay tradition could
be signified on whether it is abided or not to the rule of the school. Document
research method is solely used in this study by referring to the previous works,
theses and related journals. The findings reported in this paper highlighted that
Shāfiʿī school does not apply weak hadith in establishing the rule of Islamic law,
except as a precaution to avoid makruh conducts. Thus, if the hadith is supported
by way of mutābaʿāt and shawāhid, ijmak, qiyas, and the practice of the
companions of the prophet, it can be used as an argument in the rule establishment.
Pertaining to faḍā’il al-ʿamal issue, it has been initiated that Shāfiʿī school has not
only use weak hadith in stating reward and sin, it also used in establishing the rule
of istiḥbāb. Hence, weak hadith could not specify the certain guide of an ibadah.
