It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "Your Lord is most Merciful. If a person intends to do a good deed and then does it, a reward of ten to seven hundred good deeds, or even more, is written for him. And if he does not do the good deed, then just for the intention, one good deed is written for him. And if a person intends to commit a sin and then commits it, only one sin is written against him. But if he does not commit the sin after intending it, then one good deed is written for him. And only that person can be destroyed regarding Allah who is destined to be destroyed."
