In Your Name, my Lord, I lay my side down
Abu Hurairah, may Allah be pleased with him, narrated that :
the Messenger of Allah may the peace and blessings of Allah be upon him, said: “When one of you goes to bed, then he should take hold of the hem of his lower garment and then should clean (his bed) with the help of that for he himself does not know what he left behind him on his bed, and when he intends to lie on bed, he should lie on his right side and utter these words: ‘In Your Name, my Lord, I lay my side down, and in Your Name I raise it. if You take my soul, then have mercy upon it, and if You release it, then protect it with that which You protect Your righteous slaves (Bismika rabbī waḍa`tu janbī wa bika arfa`uhu, fa’in amsakta nafsī farḥamhā wa in arsaltahā faḥfaẓhā bimā taḥfaẓu bihī `ibādakaṣ-ṣāliḥīn)’’”
This is another Hadeeth narrated by Abu Hurayrah, may Allah be pleased with him, in which the Messenger of Allah, may the peace and blessings of Allah be upon him, commands the Muslim when he goes to bed to clean it with the help of his lower garment fearing that there may be what harms him.. then he shall say this recommended supplications.
The Prophet, may the peace and blessings of Allah be upon him, explained the reason why he commanded to clean the bed, saying: " he himself does not know what he left behind him on his bed." He does not know what happened to it after he left it.
No doubt Islam is the religion of purity and cleanliness.
The Messenger of Allah, may the peace and blessings be upon him, was the purest of people both in physical and moral traits, and used to keep his clothes and bedding clean.
The meaning of "in In Your Name, my Lord, I lay my side down ":
With your help, and thanks to the mention of your name, I put my side on my bed, and were it not for you O my Lord, I would be able to move nor to stay still, for there is no power or might except with you.
In your name, the heavens and the earth were established, and in your name their affairs as well as the affairs of their dwellers were decreed. In your name, O my Lord, I wake up. if you will,. No one may comment on your judgment or change your decree.
