The very famous haddith which say that on judgement day people will go to every prophet for intercession but only prophet Muhammad (peace be upon him) will intercede and his intercession will be accepted. But Quran say that there is NO INTERCESSION that day!!
"Then guard yourselves against a day when one soul shall not avail another nor shall intercession be accepted for her, nor shall compensation be taken from her, nor shall anyone be helped (from outside)."
(2:48).
"Then guard yourselves against a Day when one soul shall not avail another, nor shall compensation be accepted from her nor shall intercession profit her nor shall anyone be helped (from outside)."
(2:123).
"O ye who believe! Spend out of (the bounties) We have provided for you, before the Day comes when no bargaining (Will avail), nor friendship nor intercession. Those who reject Faith they are the wrong-doers."
(2:254).
"Give this warning to those in whose (hearts) is the fear that they will be brought (to judgment) before their Lord: except for Him they will have no protector nor intercessor: that they may guard (against evil)."
(6:51).
"Leave alone those who take their religion to be mere play and amusement, and are deceived by the life of this world. But proclaim (to them) this (truth): that every soul delivers itself to ruin by its own acts: it will find for itself no protector or intercessor except Allah"
(6:70).
And many more verses, doesn't this prove that haddith to be false?
