Categories of those who seek the world through the deeds of the Hereafter

Question:
If a person gives charity and his intention is that Allah will increase his wealth, or that it will cure an illness, is he among those who sought the world with his deed, such that the charity becomes forbidden, or is he forbidden because of that charity?

Answer:
Imam Muhammad ibn 'Abd al-Wahhab (may Allah have mercy on him) mentioned in his interpretation of this verse that he quoted from the scholars that they mentioned four categories in it. The first category is the one who does good deeds while he has major shirk (associating partners with Allah) in his deed. This is the ugliest of sins. The second category is the one who does a good deed not for the sake of the truth, but rather for the sake of showing off and investment, for the sake of showing off. This is the meaning: the one who shows off, whose deed is not sincere. The third category is the one who does the deed not for the sake of seeking the pleasure of Allah?
He does a good deed that is pure for the sake of Allah, containing no shirk and no harm, pure for the sake of Allah and correct according to the Sunnah of the Messenger (peace and blessings be upon him), but he does not want the reward of the Hereafter from it; rather, he wants only the worldly reward, such as giving charity in order to increase his wealth, or something else. This falls under His saying . And He guided them to their deeds. This person has no reward with Allah. The fourth category is the one who seeks the world with the deeds of the Hereafter, such as seeking knowledge for the sake of a job, seeking religious knowledge for the sake of a job, or taking on the role of imam or mu'adhdhin for the sake of a salary, or for the sake of worldly greed, and not wanting the reward of Allah, but rather wanting worldly earnings, or performing Hajj on behalf of another in order to take money.
This falls under the saying of Allah the Exalted: All these categories have no reward with Allah. However, among them are those whose deeds are nullified, such as the mushrik (one who associates partners with Allah) and the one who shows off in worship. There are also those who receive neither reward nor punishment; this is the one who does not seek the reward of the Hereafter, but only the reward of this world. Likewise, the one who performs deeds for the Hereafter but seeks thereby the world is also threatened. This is within the religion. These four categories fall under the generality of this noble verse.
As for the case where a person does a deed seeking the face of Allah and seeking the good of the world, seeking the good of both the world and the Hereafter, this is a vow . If he does a good deed that conforms to the Sunnah of the Messenger (peace and blessings be upon him) and seeks the reward of both the world and the Hereafter, that is a good thing. The discussion is about the one who wants only the reward of the world and does not want the reward of the Hereafter. Yes.
