"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."  

قَالَ رَسُولُ اللَّهِ ﷺ إِنِّي أَرَى مَا لاَ تَرَوْنَ وَأَسْمَعُ مَا لاَ تَسْمَعُونَ أَطَّتِ السَّمَاءُ وَحُقَّ لَهَا أَنْ تَئِطَّ مَا فِيهَا مَوْضِعُ أَرْبَعِ أَصَابِعَ إِلاَّ وَمَلَكٌ وَاضِعٌ جَبْهَتَهُ سَاجِدًا لِلَّهِ لَوْ تَعْلَمُونَ مَا أَعْلَمُ لَضَحِكْتُمْ قَلِيلاً وَلَبَكَيْتُمْ كَثِيرًا وَمَا تَلَذَّذْتُمْ بِالنِّسَاءِ عَلَى الْفُرُشِ وَلَخَرَجْتُمْ إِلَى الصُّعُدَاتِ تَجْأَرُونَ إِلَى اللَّهِ لَوَدِدْتُ أَنِّي كُنْتُ شَجَرَةً تُعْضَدُ  

"If you knew what I know, then you would laugh little and you would cry much."  

قَالَ رَسُولُ اللَّهِ ﷺ لَوْ تَعْلَمُونَ مَا أَعْلَمُ لَضَحِكْتُمْ قَلِيلاً وَلَبَكَيْتُمْ كَثِيرًا هَذَا حَدِيثٌ صَحِيحٌ
