If you do good to someone for the sake of Allah and he rewards you, does accepting this reward count as a deficiency in sincerity?

Question:
He says: Honorable Shaykh, may Allah grant you success. If I do good to someone intending the Face of Allah, but the one I did good to wants to reward me, does accepting this reward count as a deficiency in sincerity?

Answer:
If he initiates this and you did not look for it, it does not count as a deficiency in sincerity, because you did not intend it; rather, he is the one who did this.
