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:

[1] 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]

[2] 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]

[3] 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]
