Jami at-Tirmidhi — Chapters On Zuhd — Hadith No: 2312
Translation
Abu Dharr narrated that the Messenger of Allah (s.a.w) said:"Indeed I see what you do not see, and I hear what you do not hear. The Heavens moan, and they have the right to moan. There is no spot, the size of four fingers in them, except that there is an angel placing his forehead in it, prostrating to Allah. By Allah! If you knew what I know, then you would laugh little and you would cry much. And you would not taste the pleasures of your women in the beds, and you would go out beseeching Allah. And I wish that I was but a felled tree." [Abu 'Eisa said:] There are narrations on this topic from 'Aishah, Abu Hurairah, Ibn 'Abbas, and Anas. [He said:] This Hadith is Hasan Gharib. It has been related through routes other than this, that Abu Dharr said: "I wish that I was a felled tree." And it has been related from Abu Dharr in Mawquf form
