I met Ka'b bin 'Ujrah, may Allah be pleased with him, as he was leaving the city of the Prophet Muhammad ﷺ, on the first day of Sha'ban. So I said to him 'Where do you intend to go, O Ka'b? He said 'To the mountain. I said: 'And what will you do at the mountain, while you are leaving the neighborhood of the Prophet, peace and blessings of Allah be upon him? He said 'I am proceeding to a city where I heard the Prophet, peace and blessings of Allah be upon him, saying 'Indeed, it will come on the Day of Resurrection possessing two wings with which it flies between the heaven and the earth, made of a hollow white pearl ,hollow with its people, it calls out. 'I am Qazvin, a piece of Paradise, whoever enters me so that I may intercede for him to my Lord.
