If you been told that you cannot have any kids for any medical reason or you are having girls only and you want a boy or you been having miscarriages upon miscarriages, do the following.

Find a person who has seen the prophet in his dream. Ask him /her to do the following. 

Take pure raw cotton thread and cut seven pieces. Each piece should be measured from the hair line of the woman on the fore head till the thumb of her right foot.

Roll them together and make a rope with 7 threads.

Read Darood/Salawat 11 times

Then read Ayettal Kursi 11 times. Each time You finish Ayetal Kursi you tie a knot on the rope. And do a dam (Blow) on the knot after you have made the knot.

So in total you will tie 11 knots and blow 11 times on each knot.

Then finally read Darood/Salawat 11 times. 

Now tie this around the womans waist. That woman should never ever take it off. For example…Taking a bath, going to toile.What ever happens do not take it off.

When she becomes pregnant and she finds out that she is pregnant, she has to cook something sweet at home  and it must be white. Do not buy it from the shops. Must be cooked at home.

Now she will do a Khatim (see in the website how to do a khatim the sunni way) on the sweet thing and send the savab/Hasana of all of it and the sweet too to

Hz Seikh Abdul Qadir Jilani (Rehmatullah Alaih)

Hz Sheikh Mohammad Afzal Kanpuri (Rehmatullah Alaih)

Hz Imam Ahmad Raza Khan Barelvi (Rehmatullah Alaih). Imam of Sunnis in subcontinent. 

Then she will do 2 Rakat Nafal Salah. After the Salah facing bagdad she will say this aloud:

Ya Seikh Abdul Qadir Jilani if I had a son I will make him your slave and will name him Ghulam Muhayyud din.  

After this believe that it will be a boy. Do not doubt it. When the boy is born, after giving azan in his ears, the rope will be removed from the mother and placed around the neck of the boy. Keep it small so the child cant take it off.

Every year depending how rich you are please spend £10 or £100 pounds (or 10 or 100 in your currency) in sadaka for the boy.

When he is 11 years old  spend £1100 or if you are poor £111 or £11 (or 1100 or 111 or 11 in your currency) .Cook something sweet at home for this money and give it people as a sadaka for the boy. Once you have done that take the rope off his neck and bury it somewhere safe in the ground where people won’t step on it. 

If you are thinking why all this procedure remember this is for women who cannot have kids at all. Or they are having miscarriages and no wazifa is working. This is the last resort. You may do wazifas for hajat but if nothing works then do this. This is the last resort.
