The Messenger of Allah ﷺ said, "While I was asleep, the treasures of the earth were brought to me, and two bracelets of gold were placed in my hands. They weighed heavily upon me and troubled me. Then it was revealed to me that I should blow upon them, so I blew upon them and they vanished. I interpreted them as the two liars between whom I stand, the one of Sana and the one of Yamamah."
وقال رسول الله ﷺ بينما أنا نائم أوتيت بخزائن الأرض فوضع في يدي سواران من ذهب فكبرا علي وأهماني فأوحي إلي أن انفخهما فنفختهما فذهبا فأولتهما الكذابين اللذين أنا بينهما صاحب صنعاء وصاحب اليمامة
