Is Dajjal mentioned in the Quran?

                                                                             
 Shaykh Abu Amr Al Hajooree حفظه الله mentioned in his explanation of Qatfu Thamar Fi Bayaan Aqeedait Ahli Athar of Al Imam Al Allamah Sidewq Hassan Khan Rahimahullah Volume 2 Page 552-553,

Many from the mufasireen mentioned with His saying exalted be He,

يَوْمَ يَأْتِي بعض آياتِ رَبِّكَ لاَ يَنفَعُ نَفْساً إِيمانهَا لَمْ تَكُنْ آمَنَتْ مِن قَبل أَوْ كَسَبَتْ إِيمَانِها خَيراً

The day that some of the Signs of your lord do come, no good will it do to a person to believe them, if he believe not before, nor earned good (by performing deeds of righteousness) through His Faith. [Surah Al An'am 158]

That these signs are, the raising if the sun from where it sets (the west), and the Dajjal, and the beast (of the earth) and they qouted as evidance the hadeeth of Abu Hurairah with Muslim (158), that the messenger  
صلى الله عليه وسلم, said, Three if they appear "no good will it do to a person  to believe then, if he believed not before, nor earned good (by performing deeds of righteousness) through his Faith" the rising of the sun from where it sets (the west), and the Dajjal, and the beast of the earth."

End Qoute.

Also as an extra benefit, As Shaykh Al Allamah Rabee Ibn Hadee Al Madkhalee حفظه الله mentioned in his explanation of Sharhus Sunnah,

"And will follow him (Dajjal) 70 thousand from the Jews of Asbahan, and he is the Mahdi of the Jews which they are waiting for, so there Mahdi it is Dajjal, and for the Rawafid is the Mahdi they originated, and they claim that he is hidden in the tunnel, and they shroud aroun it from the tales, and the most false of the affairs, which neither the Jews or the Christians say similar to in regards to the companions of there prophets!"
