Salafus Saaliheen (Pious Predecessors)

Moulana Ashraf Ali Thanwi (rahimahullah) being a Mujaddid

Q: Is there ijma of Ulama that Moulana Ashraf Ali Thanwi (rahimahullah) was the mujadid that Nabi (sallallahu alaihi wasallam) mentioned for every hundred years?

Is the qawl that Moulana Ilyaas (rahimahullah) was a mujaddid in tableegh and Moulana Ashraf Ali Thanwi (rahimahullah) in tasawwuf and another great aalim in another field like Jihad? (Maybe the Afghan people. Masha Allah they are great fighters in Allah's path).

If someone says that no one knows Moulaaa Ashraf Ali Thanwi (rahimahullah) in hijaaz, so how was he the Mujadid? (Obviously he was. From what I know from reliable sources). How should one reply? 

Muhammad al Faatih

Q: My question pertains to Muhammad al Faatih. Most of Ahlus Sunnah wal Jama'a believe that he was the blessed conqueror prophecised in the Hadith. However, some from the Salafiyyah at my Uni believe that he was not and the Hadith is referring to the Mahdi. In turn, they say some horrendous things against Muhamad al Faatih and incriminate him with incest, drinking and other Kaba'ir. These Salafi's are doing a lot of damage to the Muslims at my campus. A Shaikh once told me that there is Ijma' of the scholars that Muhammad al Faatih was the conqueror of Constantinople that was referred to in the Hadith. Can I please request as many references to scholars and citations of consensus that Muhammad al Faatih was in fact the one Prophecised in the Hadith? This will help me alleviate the confusion and doubts that the Salafis are imbuing in the minds of the Muslims.
