A bad deed done: one bad deed

السيئة المعمولة: سيئة واحدة

Whoever intends a bad deed and does it, God writes it as one bad deed Muslim 131 — God has written good deeds and bad deeds, and the Qur'an states that whoever brings a bad deed is repaid only its like Qur'an 6:160 Qur'an 40:40. The bad-deed side is counted in ones while the good-deed side starts at ten: this is the asymmetry on which the calculator builds its two columns.
