Quran 2:135 from Surah Al-Baqara on Divine Marvels.
وَقَالُواْ كُونُواْ هُودًا أَوۡ نَصَٰرَىٰ تَهۡتَدُواْۗ قُلۡ بَلۡ مِلَّةَ إِبۡرَٰهِـۧمَ حَنِيفٗاۖ وَمَا كَانَ مِنَ ٱلۡمُشۡرِكِينَ
English translation: And they said Be Jews or Christians (then) you will be guided Say Nay (the) religion (of) Ibrahim (the) upright and not he was of those who associated partners (with Allah)
Transliteration: waqalu kunu hudan aw nasara tahtadu qul bal millata ib'rahima hanifan wama kana mina al-mush'rikina
