Is a Muslim rewarded if someone imitates him without his knowledge, or sees him adhering to the apparent Sunnah, and then remembers Allah and performs a righteous deed?

The Holy Quran highlights the importance of good role models and their profound impact, while condemning the imitation of falsehood. The Prophet, peace and blessings be upon him, said: "Whoever calls to guidance will have a reward equal to the rewards of those who follow him." Therefore, whoever's uprightness and character become a cause for another's guidance or commitment, will be rewarded for it, provided they are free from hypocrisy and their intention is pure.
