Does a Muslim receive a reward for his intention to do good if he forgets this act after resolving to do it, with evidence from the Qur'an and Sunnah?

Whoever resolves to do a good deed—such as a good intercession—but does not do it, Allah the Almighty records a reward for him for his intention, because the Prophet, peace and blessings be upon him, said: "Whoever intends to perform a good deed, but does not do it, Allah records it with Him as a complete good deed."
