And if they think that they are the Truthful Ones...

According to Qur'an, Even the Shirts of Prophets (as) can benefit / help us Allah testifies in Qur'an that even the Shirt of Prophet Yousuf (as) was able to benefit the others, and had the power of giving sights to the blind.

With this verse in mind we would like to pose some questions to the Salafi: Can anybody still deny the witness of Qur'an and say that it is associating partners to Allah, when we say that the shirt of Yusuf (as) also got the power to benefit others? Did Prophet Yaqoob (as) commit shirk by seeking the benefit/help from the Shirt of Yusuf (as), instead of asking it DIRECTLY from Allah?

If simply the shirt of 'a' Nabi (a material possession 'non-living') has the power to restore one's eyesight, then by the same token why is it Bidahto seek blessings / cure by touching the grave of Rasulullah (s) who was after all the Chief of all Prophet's? Would touching a shirt have greater healing powers than touching the grave of Rasulullah (s)? If the Salafi claim that Rasulullah (s) is DEAD, then what about a Shirt is that a living organism?

Umm Salama used to seek help / benefit from Hairs of Rasool Allah [saww] against Diseases and against the Evil Eye Bukhari narrates in his Sahih in the Book of Clothing, under the chapter entitled "What is mentioned about gray hair: Uthman bin Abd Allah ibn Mawhab said, "My people sent me with a bowl of water to Umm Salama." Isra'il approximated three fingers indicating the small size of the container in which there was some hair of the Prophet.
