Al-A'raf - 7:180

وَلِلّهِ الأَسْمَاء الْحُسْنَى فَادْعُوهُ بِهَا وَذَرُواْ الَّذِينَ يُلْحِدُونَ فِي أَسْمَآئِهِ سَيُجْزَوْنَ مَا كَانُواْ يَعْمَلُونَ
[7:180]
And Allah's are the best names, therefore call on Him thereby, and leave alone those who violate the sanctity of His names; they shall be recompensed for what they did.
The most beautiful names belong to Allah: so call on him by them; but shun such men as use profanity in his names: for what they do, they will soon be requited.
Allah's are the fairest names. Invoke Him by them. And leave the company of those who blaspheme His names. They will be requited what they do.
