Al-Kafirun before sleep
قُلْ يَـٰٓأَيُّهَا ٱلْكَـٰفِرُونَ لَآ أَعْبُدُ مَا تَعْبُدُونَ وَلَآ أَنتُمْ عَـٰبِدُونَ مَآ أَعْبُدُ وَلَآ أَنَا۠ عَابِدٌ مَّا عَبَدتُّمْ وَلَآ أَنتُمْ عَـٰبِدُونَ مَآ أَعْبُدُ لَكُمْ دِينُكُمْ وَلِىَ دِينِ

Say, "O disbelievers, I do not worship what you worship. Nor are you worshippers of what I worship. Nor will I be a worshipper of what you worship. Nor will you be worshippers of what I worship. For you is your religion, and for me is my religion."
