Riyad as-Salihin

Ibn 'Abbas (May Allah be pleased with them) reported: Ukaz, Mijannah and Dhul-Majaz were markets during the pre-Islamic period. The Companions disliked trading there till the following Ayat of the Noble Qur'an were revealed: "There is no sin on you if you seek the Bounty of your Rubb (during pilgrimage by trading)..." (2:198)
