In The Name of Allaah, The Most Merciful, The Bestower of Mercy
It used to be said that whoever perpetrates these three acts will be haunted by them:
 Rebellion against Allaah’s commandments. Allaah (The Most High) said:
يَا أَيُّهَا النَّاسُ إِنَّمَا بَغْيُكُمْ عَلَىٰ أَنْفُسِكُمْ
O mankind! Your rebellion (disobedience to Allah) is only against your ownselves.
[Soorah Yoonus: Ayah: 23]
 Evil plotting. Allaah (The Most High) said:
وَلَا يَحِيقُ الْمَكْرُ السَّيِّئُ إِلَّا بِأَهْلِهِ
But the evil plot encompasses only him who makes it.
[Soorah Faatir: Ayah: 43]
 Breaking pledges. Allaah (The Most High) said:
فَمَنْ نَكَثَ فَإِنَّمَا يَنْكُثُ عَلَىٰ نَفْسِهِ
Then whosoever breaks his pledge only breaks it to his own harm.
[Soorah Al-Fath: Ayah: 10]
