all the Hadith which imply that Muhammed (sallahu alaihay wassallam) is/was the reason for creation of this universe (Maqsood-e-Kainaat) are mawdo/dhaeed)

1. There is no reason for claiming the fabrication of such Ahaadith. In fact, there is no contradiction whatsoever between this verse of the holy Qur'aan and those Ahaadith. Because, although the world was created for the purpose of worship, it was Rasulullah (Sallallaahu Alayhi Wasallam) who was the best and most exalted worshipper of Allah and this Aayat implies that if it were not for those who worshipped Allah, He would have not created man and Jinn.
Moreover, this Aayat only discusses the purpose and not the reason for the creation of man and Jinn only, whereas those Ahaadith discuss the reason and not the purpose for which the entire universe (and not only man and Jinn) was created. Allah Ta'ala says in the holy Qur'aan, 'And we have not sent you except as a mercy for the worlds'. It is accepted by one and all that if this was not for the mercy of Allah, the universe would not remain intact even for a single moment. And in this case, Rasulullah (Sallallaahu Alayhi Wasallam) was chosen as the form of that mercy. So, it would be safe to say, 'If it were not for Rasulullah (Sallallaahu Alayhi Wasallam), the world would have not been in existence.'
2. We do not see any reason for the discouraging of the collar.

and Allah Ta'ala Knows Best
