It is narrated from Sayyiduna Abu Dharr (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) recited this verse: «هَلْ أَتَى عَلَى الْإِنْسَانِ حِينٌ مِنَ الدَّهْرِ لَمْ يَكُنْ شَيْئًا مَذْكُورًا» “Indeed, there came upon man a period of time when he was not a thing [even] mentioned.”(75: Al-Insan: 1) Then he said:“Surely, what I see you cannot see, and what I hear you cannot hear. (Listen) The heavens creak, and it is their right to creak, for there is not a space of four fingers in them except that there is an angel prostrating. By Allah! If you knew what I know, you would laugh little and weep much, you would abandon the enjoyment with your wives on your beds, and you would go out to the hills beseeching Allah.”
