Guru Nanak Dev Ji (tere dost lagdey ney, satkaar naal nahee bulaa sakda?) has mentioned the Quran in gurbani just like the `vedas.` we`ve already been through this just do a search on the forum.
I will quote.
mihar maseeth sidhak musalaa hak halaal kuraan.
saran sunanth seel rojaa hohu musalmaan.
Let mercy be your mosque, faith your prayer-mat, and honest living your Koran.
Make modesty your circumcision, and good conduct your fast. In this way you shall be a true musulmaan.
