Hilal bin Yasaf (may Allah have mercy on him) said: I was in Basrah and I entered the mosque, and there was an elderly man with people gathered around him, and he was narrating hadith to them. I heard him say: The Messenger of Allah (peace and blessings be upon him) said: "The best of people is my generation, then those who come after them, then those who come after them, then those who come after them. Then after them people will come who will be fat and will love obesity, and who will give testimony before they are asked for it." I asked: "Who is this?" The people said: "Sayyiduna Imran bin Husayn (may Allah be pleased with him)."
