How many Zaydi Madhabs are there in general?

Thank you for your questions!

1. Is there any book dedicated to Fiqhi rulings of imam Jafar and imam Baqir ( peace be upon them both )

No. The judgements of Imams al-Baaqir and as-Saadiq, upon them be peace, are scattered throughout our texts, such as the Ahkaam, Al-Bahr, and others. It would be rather impossible to follow their judgements exclusively since we have no reliable source of their fiqh which is comprehensive enough. Instead, one can simply follow the mainstream Zaydi fiqh since there is really no disagreement amongst our imams in terms of halaal and haraam. Interestingly enough, we mentioned in our introduction to our translation of the Ahkaam that there was a perceived disagreement between Imams ‘Abdullah al-Kaamil and Ja’far as-Saadiq, upon them be peace, the latter said: “By Allah and by this edifice to which I direct myself to! I have been lied upon; our madhhab is the same!” So, not only does Imam as-Saadiq affirm that he has been lied upon and falsely attributed, but also he says that there is no differences between his opinion and that of the other imams of Ahl al-Bayt, upon them be peace.

2. What if i dont have any clean surface to prostrate which is natural around me, can i use a turbah in such a case to follow something mustahhab?

According to our imams, it is permissible to prostrate on a turbah provided that one does not believe that there is inherent virtue in such (Ref. Al-Jawaab al-Kaashif). It is praiseworthy to prostrate on something organic; however, there is no problem in prostrating on carpet, fabric, or any other inorganic material (Ref. Al-I'tisaam).

One should also keep in mind that prostrating on something applies not only to the forehead but to all seven limbs. So, I am amazed at those who insist on prostrating on turbah when only their forehead touches it and not the rest of their limbs. Similarly, the nose is included with the head in the prostration, so why is it that the Imamis prostrate with their forehead touching the turbah and not their noses also?

3. Whats the view on Tabarruk?

InshaAllah, I will look into this and get back to you.

4. How many zaydi Madhabs in fiqh are there?

I don't understand this question. There are no multiple fiqh madhaahib in the Zaydi school.  

5. How does one combine wiping the feet and washing them if i follow the stance of imam Nair AS.

You simply wash the feet along with wiping.

And Allah knows best!

As salaamu alaykum wa rahmatullahi wa barakatuhu!

Oh ok. Thanks for the clarification! I would concur with Br Ibn Kamal on this point. The Hadawi 'madhhab' is not the collected opinions of imam al-Haadi, alayhi salaam, but rather the collective opinions of the imams. That is why in texts such as Al-Muntakhab, the imam frequently says: "My opinion and the opinion of the scholars of Ahl al-Bayt..." or "We say..." ('We' meaning the Ahl al-Bayt) or "Those other than us say..." etc. In rare cases, he makes his own personal ijtihaad, but in keeping with his minhaj, he explicitly states when he uses his own opinion so as to not confuse it with the collective judgements he received from the imams and scholars of the Prophetic Progeny. We explain this in detail in our introduction to the translation of al-Haadi's Ahkaam.

And Allah knows best!

Oh yeah, regarding the question about tabarruk, or seeking blessings from creation, the only reference in Zaydi sources I was able to find was the recommendation for one to catch some of the first drops of rain and rub it on one's body and clothes to seek blessings from it. It is said to be based on the fact that Allah calls rain {blessed} in the Qur´an as well as the practice of the Prophet, peace and blessings be upon him and his progeny, and that of 'Ali, upon him be peace (Ref. Al-Bahr).

And Allah knows best!
