What is the ruling on saying "You heal me, You cause me to die and give me life" as a metaphorical slogan, and is the one who says it excused by ignorance if it contains sin?

Using this slogan (meaning: The spring made the vegetables grow) is permissible if it is free from two things:

1. That the listener or reader does not imagine that it attributes the action to other than Allah in reality. 2. That it does not originate from someone known for uttering blatant disbelief in words and deeds.

If it is free from these two prohibitions, then its use is permissible. It falls under figurative attribution (al-majaz al-aqli), which is the attribution of an action or what it implies to something associated with it, other than what it truly belongs to, through interpretation.

The scholar al-Sahsawani holds that figurative attribution (al-majaz al-aqli) is not to be rejected, but with detail:

If in the speech of believers there is an attribution of what a servant is capable of (like eating and drinking) to other than Allah, it must be interpreted literally, not figuratively. If in their speech there is an attribution of what only Allah is capable of (like "so-and-so cured me"), it must be interpreted as figurative attribution (al-majaz al-aqli), provided that the speaker has not uttered blatant disbelief in words and deeds; otherwise, their speech is not to be interpreted figuratively. If someone from among the worshipers of prophets and righteous people says: "O so-and-so, cure my sick person," if the intended meaning is a real attribution, it is disbelief and polytheism. If the intended meaning is a figurative attribution ("be a cause for the healing of my sick person"), then if the supplicated person is alive and present, it is not polytheism but it suggests polytheism, so it should be abandoned. However, if the supplicated person is alive but absent, or dead and called upon from a distant place from the grave, this is polytheism. And if the supplicated person is dead and called upon at their grave, it is not polytheism but an innovation (bid'ah).

Therefore, a believer should absolutely avoid supplicating to anyone other than Allah.
