For a diabetic patient: Take an organic egg, in a bowl take enough lemon juice that the egg is soaked in it completely. This is to be done in the evening then in the morning peel the egg and separate the yolk, then mix the white of the egg with the lemon juice, if yolk is also mixed in the lemon juice do not drink it then because it is a poison. Drink the lemon juice mixed with egg white, do not worry if you vomit or anything else happens. Do this regularly for 3 days. Then do the above leaving 1 day then do it on the 2^nd day then leave 2 days then do it on the third day similarly just keep on doubling the days like this, 1 egg should be eaten in a month, leave one month and eat 1 egg in the next month. Eat sweet, there are no precautions. If Allah wills this is a complete cure for diabetes.  (Fazl Subhan, Mianwali)
