Hammam bin Munabbih, may Allah have mercy on him, says that once I visited Madinah Munawwarah. I saw a study circle near the pulpit in Masjid Nabawi. I asked the people, "Whose circle is this?" The people replied, "This is the circle of Hazrat Abu Hurairah, may Allah be pleased with him." I also asked Hazrat Abu Hurairah, may Allah be pleased with him, a question. He said, "Where are you from?" I replied, "I am from the people of Yemen." Upon hearing this, he said, "I heard my beloved Prophet (peace and blessings be upon him) say: 'Faith and wisdom are very excellent among the people of Yemen. These people are soft-hearted, whereas the hardness of hearts is among the owners of camels,' and he pointed with his hand towards the east."
