إِنَّ عِدَّةَ الشُّهورِ عِندَ اللَّهِ اثنا عَشَرَ شَهرًا في كِتابِ اللَّهِ يَومَ خَلَقَ السَّماواتِ وَالأَرضَ مِنها أَربَعَةٌ حُرُمٌ ۚ ذٰلِكَ الدّينُ القَيِّمُ ۚ فَلا تَظلِموا فيهِنَّ أَنفُسَكُم ۚ وَقاتِلُوا المُشرِكينَ كافَّةً كَما يُقاتِلونَكُم كافَّةً ۚ وَاعلَموا أَنَّ اللَّهَ مَعَ المُتَّقينَ

“There are twelve months with Allah in the Book of Allah, from the day He first created the heavens and earth. Four of them are sacred. That is the true religion and way of life. So do not wrong one another during them. However, fight the idolaters totally just as they fight you totally, and know that Allah is with those who have piety.” — Qur’an 9: 36

وقال علي بن أبي طلحة، عن ابن عباس قوله {إِنَّ عِدَّةَ الشُّهُورِ عِنْدَ اللَّهِ اثْنَا عَشَرَ شَهْرًا} الآية {فَلا تَظْلِمُوا فِيهِنَّ أَنْفُسَكُمْ} في كلِّهن، ثم اختص من ذلك أربعة أشهر فجعلهن حراما، وعَظم حُرُماتهن، وجعل الذنب فيهن أعظم، والعمل الصالح والأجر أعظم
