Every AM and PM, recite three times the following words of Sayyidina Muhammad, Sallallahu Alaihi wa Sallam:
Wa Laa Fis-Samaa-i,
Wa Huwas-Samee'ul 'Aleeem.
AFTER THAT, with or without Wudu, recite Qul A'oodhu Birabbil Falaq and Qul A'oodhu Birabbin-Naas, three times each, cup your hands, blow in them and rub your hands all over your body, whatever parts you can.
Those two Surahs, the last ones in the Qur'an, are called the Two Protectors.
