Hazrat Abdullah says that if a person intends to commit a sin or evil, it is not written until he actually does it. But if someone intends to commit a sin in the Haram, such as planning to kill near Masjid al-Haram, then Allah the Exalted will make him taste a painful punishment. Then he recited this verse from Surah Al-Hajj, { وَ مَنْ یُّرِدْ فِیْہِ بِاِلْحَادٍ بِظُلْمٍ }.
