It is narrated from Qays bin Ubad that he said: I was sitting in a circle in the mosque when a man entered. The people said: This is a man from the people of Paradise. He prayed and left, and I followed him and said to him: The people have said such and such (about you). He said: It is not permissible for anyone to lie or to say what he does not know, and I will tell you the reason for this. I saw a dream which I related to the Prophet (peace and blessings be upon him). I saw as though I were in a green garden (he described its vastness and its greenery), and in the very middle of the garden was a pillar of iron. A man came to me and said to me: Climb it. I said: I am not able to climb. He said: Then a servant came from behind me and supported me, and lifted me up along with my clothes. When I reached the very top of the pillar, there was a ring there, and I put my hand into the ring. When I woke in the morning, the ring was as though still in my hand. The Prophet (peace and blessings be upon him) said (interpreting it): "As for the garden, it is the garden of Islam; as for the pillar, it is the pillar of Islam; and as for the ring, you have taken hold of the firmest handhold (al-'urwah al-wuthqa), and you will remain steadfast upon Islam until you die." This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim); had the name of the man in it been known, it would be sahih on the condition of both of them.
