Mukhtasar Bukhari

Narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that the Noble Prophet (peace and blessings of Allah be upon him) said among other Qudsi narrations: “Allah Almighty has written down good deeds and bad deeds and has made it clear which is a good deed and which is a bad deed. So whoever intends to do a good deed but does not do it, Allah will write a complete good deed in his record. And whoever intends to do a good deed and then does it, Allah will write for him ten to seven hundred good deeds, or even more, as much as He wills. And whoever intends to do a bad deed but refrains from doing it (out of fear of Allah), Allah will write a complete good deed for him. And whoever intends to do a bad deed and then does it, only one sin will be written for him.”
