Sayyiduna Ibn Abbas (may Allah be pleased with him) said: The Messenger of Allah (peace and blessings be upon him) and his Companions (may Allah be pleased with them) came to Makkah while the fever of Yathrib had weakened them. The polytheists said: "Tomorrow a people are coming to you whom the fever of Yathrib has weakened and who have suffered great hardship from it." So they sat on the side of the Hijr (Hatim), and the Prophet (peace and blessings be upon him) commanded them to perform ramal for three rounds and walk between the Corners, so that the polytheists would see their strength. The polytheists then said: "These are the ones you claimed the fever of Yathrib had weakened? These are stronger than so-and-so!" Sayyiduna Ibn Abbas (may Allah be pleased with him) said: Nothing prevented them from performing ramal in all the rounds except mercy towards them.
