Is saying to a person: "Illness does not harm God" correct, or is it one of the afflictions of the tongue?

It is preferable to avoid the phrase "Allah's patient" out of reverence for Allah, following the prophetic supplication: "And evil is not attributed to You," and Abraham's saying: "And when I am ill, it is He who cures me." Here, the illness was attributed to Abraham himself, not to Allah. While the intention behind it might be to express Allah's mercy towards the sick, which is permissible if that is the intent or if it is used in the sense of "Allah's guest," it is nevertheless better to avoid it to prevent any perceived disrespect towards Allah.
