A prescription for sleep
Honourable Hakeem Sahib Assalam alaikum! You asked to send prescription for inducing sleep. Many people complain about insomnia, anaemia being the cause of it. If someone suffers from insomnia, he should take medical prescription/tablets for increasing haemoglobin. Besides this, it is our 10 years experience that whosoever is unable to sleep and he recites

بِسْمِ اللہِ الرَّحْمٰنِ الرَّحِیْمِ اَعُوْذُ بِکَلِمَاتِ اللہِ التَّامَّاتِ مِنْ غَضَبِہٖ وَعِقَابِہٖ وَ شَرِّ عِبَادِہٖ وَمِنْ ھَمٰزَاتِ الشَّیَاطِیْنِ وَاَنْ یَّحْضُرُوْنِ ‘‘ (بخاری شریف) 

 his complaint shall be relieved. 

(Zahid Allah, banu)
 
A medical treatment for insomnia
A medical treatment for insomnia is to immerse 7 peeled almonds in water overnight and eat them one by one fasting( space for urdu text) , in the morning. Massage scalp with almond oil. Its spiritual treatment is to recite surah qadur while looking towards the sky after every ablution. I have been practicing this for a long time and found it useful. I have read in many books that if person is unable to go to sleep he should lie down and imagine that he is present in heights of the sky, floating in the air, flying in the skies among the stars. With this he will start feeling sleepy.
