This question is a bit tricky, as there is no definitive answer in Islamic history or literature. We don't find specific physical descriptions of the Sahaba (Companions of the Prophet Muhammad) in detail, including their leg sizes.
It is important to remember that focusing on physical characteristics like leg size is not something emphasized in Islamic teachings. The Sahaba were primarily known for their piety, character, and contributions to the spread of Islam.
Therefore, it is not appropriate to speculate or spread rumors about the physical appearance of the Sahaba.
