What is the ruling on a woman prostrating (in prayer) when her child has died, and she has endured with patience, seeking reward from Allah? Is her action correct?

The prostration of a woman upon hearing the news of her husband's death was not well-known among the Salaf. What was well-known among them was to say "Innā lillāhi wa innā ilayhi rājiʿūn" (To Allah we belong and to Him is our return), to seek reward from Allah, and to be content with Allah's decree. This matter hinges on the woman's intention. If she prostrates to ask Allah for patience or anything else that is legislated, then it is permissible. However, dedicating oneself to prostration without a compelling reason is not legislated. Scholars have agreed that prostration is an act of worship if there is a legal reason for it, such as prostration in prayer, for forgetfulness, or for reciting a verse of prostration. As for prostration without a reason, its permissibility as an act of worship is a matter of scholarly disagreement. Some have permitted it in response to verses that indicate Allah's power, such as the occurrence of calamities, while others have disliked it and absolutely forbidden it due to the absence of a compelling reason.
