The Imam replied...
The Imam replied: As for events that may occur (al-hawadith al-waqi'a) [when you may need guidance] refer to the transmitters (ruwat) of our teachings who are my Hujjah (proof) to you and I am the proof of God (Hujjatullah) to you all [^2]. Shaykh al-Tusi also transmits the narration in the book ‘al- Qayba’[^3] and other collections of Imami ahadith report the tradition from the books mentioned above.
Advocates of Wilayat al-Faqih often refer to the second part of the tradition, namely, “they are my proof to you, and I am the proof of God to you all” to establish the authority of the fuqaha. However, some scholars (such as Imam Khomeini) maintain that the first part of the hadith may also be used to establish the authority of the faqih.
The first section of this narration encourages people to ask those who relate the traditions of the Imams (peace be upon them) about any new occurrences that they encounter. It is highly unlikely that Ishaq ibn Yaqub asked the Imam about what was to be done regarding religious questions; even ordinary Shi’a would know that in these cases of fiqh (jurisprudence) one should refer to the fuqaha (jurists).
In fact, according to some narrations, people would recourse to the students of an Imam during his lifetime. Therefore, Ishaq must have been referring to something other than this by his question about ‘al-hawadith al-waqi’a’, Imam Khomeini says: What is meant by hawadith al-waqi'a is rather the newly arising problems that affect the people and Muslims.
The question Ishaq ibn Yaqub was implicitly posing was this: now that we no longer have access to you, what should we do with respect to social problems? What is our duty? [^4] It is necessary to establish what the Imam meant by ‘ruwat’ (narrators), when he commands his followers to refer to the narrators of traditions with respect to these new circumstances.
After all, it is self evident that people who merely transmit traditions and narrate what they have seen and heard, without a comprehensive understanding of the science of ahadith or jurisprudence, are not qualified to undertake this duty. Therefore the Imam must have been referring to the fuqaha (jurists) who are experts in the interpretation and explanation of Islamic sources.
We mentioned earlier that most Imami jurists usually refer to the second part of this tradition to establish the guardianship of the jurists.
