Surah Al-Hadid (The Iron), Verse 29

لِّئَلَّا یَعْلَمَ اَهْلُ الْكِتٰبِ اَلَّا یَقْدِرُوْنَ عَلٰی شَیْءٍ مِّنْ فَضْلِ اللّٰهِ وَاَنَّ الْفَضْلَ بِیَدِ اللّٰهِ یُؤْتِیْهِ مَنْ یَّشَآءُ وَاللّٰهُ ذُو الْفَضْلِ الْعَظِیْمِ 

Li'alla ya'lama Ahlul kitaabi allaa yaqdiroona 'alaa shai'in min fadlil laahi wa annal fadla bi Yadil laahi yu'teehi many yashaaa'; wallaahu Zul fadilil 'azeem

“That the People of the Book may know that they have no power whatever over the Grace of Allah, that (His) Grace is (entirely) in His Hand, to bestow it on whomsoever He wills. For Allah is the Lord of Grace abounding.”
