(Postponement (of a sacred month) is only an excess of disbelief) He says: postponement of the month of Muharram to the month of Safar is an excess of disbelief (whereby those who disbelieve are misled) they are wrong to postpone Muharram to Safar, (they allow it) i.e. Muharram (one year) and thus fight in it (and forbid it) i. e. Muharram ((another) year) and thus abstain from fighting during it. And so when they used to do this, Muharram would not be considered sacred while Safar became sacred instead, (that they may make up) that they may match (the number of the months which Allah hath hallowed) four in number, (so that they allow that which Allah hath forbidden) i.e. Muharram. (The evil of their deeds is made fair-seeming unto them. Allah guideth not) leads not to His religion (the disbelieving folk) those who do not deserve it. The one who used to postpone the sacred months was a man called Nu'aym Ibn Tha'labah.

إِنَّمَا النَّسِيءُ زِيَادَةٌ فِي الْكُفْرِ ۖ يُضَلُّ بِهِ الَّذِينَ كَفَرُوا يُحِلُّونَهُ عَامًا وَيُحَرِّمُونَهُ عَامًا لِيُوَاطِئُوا عِدَّةَ مَا حَرَّمَ اللَّهُ فَيُحِلُّوا مَا حَرَّمَ اللَّهُ ۚ زُيِّنَ لَهُمْ سُوءُ أَعْمَالِهِمْ ۗ وَاللَّهُ لَا يَهْدِي الْقَوْمَ الْكَافِرِينَ
Intercalating a month is adding to unbelief. The unbelievers are misguided by this, for they take the same month to be sacred one year and sacrilegious the next, thus making the number of months sanctified by God accord with theirs in order to make what God has forbidden, lawful. Attractive seem to them their evil deeds; but God does not show the unbelievers the way.
