It is narrated from Sayyiduna Abu Dharr (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "I see things that you do not see and I hear things that you do not hear. The sky creaks, and it is right for it to creak, for there is no space of four fingers in it except that there is an angel prostrating there. If you knew what I know, you would laugh little and weep much, and you would abandon enjoying your wives in your beds, rather you would go out to the deserted roads (and wildernesses) and cry out to Allah the Exalted." After narrating this hadith, Sayyiduna Abu Dharr (may Allah be pleased with him) said (it is apparent that the students of Abu Dharr are narrating about him): "By Allah! I wish I were a tree that would be cut down."
