Sayyiduna Ibn Abbas (may Allah be pleased with them both) said: When the Messenger of Allah (peace and blessings be upon him) conquered Makkah, he said: "Indeed Allah, the Mighty and Majestic, and His Messenger have forbidden to you wine and its price, have forbidden to you carrion and its price, and have forbidden to you swine, eating it and its price."
And he said: "Trim the moustaches, let the beards grow, and do not walk in the markets without wearing a lower garment. Whoever acts upon the way of others than us is not one of us."
