Could you please clarify Fatwa No. 103521, taking into account the medical aspect and the effect of certain foods on increasing or decreasing flatulence?

The lack of clarity in the aforementioned fatwa is not apparent. To clarify it, the problematic point must be identified. As for foods that reduce flatulence, this is not within our specialization. One should ask medical professionals. Assigning a person the task of searching for them might involve hardship that abrogates the obligation, as Allah Almighty says: "And He has not placed upon you in religion any difficulty."
