It is reported that Qabisah ibn al-Mukhariq said: "I came to the prophet (PBUH), and he asked me, what brings you here Qabisah?'. I replied: I have grown old and my bones have grown weak, so I have to come to you that you may teach me something by which Allah may benefit me'. He told me: 'O Qabaisah, every stone, tree or pieces of clay that you pass asks Allah's forgiveness for you. Qabisah, when you have prayed the dawn prayer, say this three times: 'Most Glorified is Allah Almighty; all praise be to him! (Subhan Allah al-Azim w bi-Hamdih)'. You will then by protected from blindness, leprosy and semi-paralysis. Qabisah, say: 'O Allah, I ask you of what you have. Grant me of your generosity, cover me with your mercy, and send down your blessings upon me (Allahuma inni As'aluka mimma indak, w afid alyya min fadlek, wanshur alyya min rahmatik, wa'anzel alyya min barakatek)"'.
