Is sending a promotion research paper to a journal whose editor-in-chief is someone one fears might cause harm to the researcher considered reliance on Allah, or is it obligatory to take precautions, given that there is no other journal of the same high standing?

Knowing that reliance on God alone is the path to success and salvation, and that God is capable of everything, is not a blameworthy idleness. Rather, blameworthy idleness is abandoning effort and neglecting to take means, under the pretext that reliance on God in the heart is sufficient. A servant must have his heart reliant on God, and he must take the commanded means while relying on God. Therefore, it is necessary to take means while relying on God Almighty.
