Holy Quran » AZ ZUMAR : 65

And it was already revealed to you and to those before you that if you should associate [anything] with Allah , your work would surely become worthless, and you would surely be among the losers."

{ ولقد أوحيَ إليك وإلى الذين من قبلك } والله { لئن أشركت } يا محمد فرضا { ليحبطن عملك ولتكوننَّ من الخاسرين } .
