[دموع الشرقية]

Imam Ali peace be upon him said that who keeps the following Dua' written on a skin of Deer, he/she will be safe from any of the magic influence

بسم الله .. وبالله ولا قوة إلا بالله
قال موسى ما جئتم به السحر إن الله سيبطله ، إن الله لا يصلح عمل المفسدين
فوقع الحق و بطل ما كانوا يعملون ، فغلبوا هنالك و إنقلبوا صاغرين

[In the name of Allah and with Allah: in the name of Allah-that which Allah wills (takes place); in the name of Allah- there is no power nor strength saves with Allah. Musa said: What you have brought is sorcery; verily Allah will soon make it vain: verily Allah does not put in order the work of the mischief-makers.
Thus the truth was established, and what they were doing was made vain. So there and then (Faroun and his enchanters) were defeated and made to look small, humiliated]
