It is narrated from Sayyiduna Abu Dharr (may Allah be pleased with him); he said that the Messenger of Allah (peace and blessings be upon him) said: "Indeed, I see what you do not see and I hear what you do not hear. The heaven groans (under its weight) and it has the right to groan; there is not a space in it the size of four fingers except that an angel has placed his forehead there in prostration before Allah. By Allah, if you knew what I know, you would laugh little and weep much, you would not take pleasure with women on beds, and you would go out to the hills and open plains, crying out imploringly before Allah." (Hearing this, Sayyiduna Abu Dharr (may Allah be pleased with him) said:) "By Allah, I wish that I were a tree that is cut down." This hadith has a sahih (authentic) chain on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it.
