Verse 37

إِنَّمَا ٱلنَّسِىٓءُ زِيَادَةٌ فِى ٱلْكُفْرِ يُضَلُّ بِهِ ٱلَّذِينَ كَفَرُوا۟ يُحِلُّونَهُۥ عَامًا وَيُحَرِّمُونَهُۥ عَامًا لِّيُوَاطِـُٔوا۟ عِدَّةَ مَا حَرَّمَ ٱللَّهُ فَيُحِلُّوا۟ مَا حَرَّمَ ٱللَّهُ زُيِّنَ لَهُمْ سُوٓءُ أَعْمَـٰلِهِمْ وَٱللَّهُ لَا يَهْدِى ٱلْقَوْمَ ٱلْكَـٰفِرِينَ

Indeed forgetting it increases disbelief. Thus, the unfaithful mislead therewith, they allow it one year and prohibit it the next year in order to nullify the number that God has prohibited and they permit what God has prohibited. Adorned for them are their evil deeds. And God does not guide the unfaithful.
