Everytime, before  my husband goes to work, he wants to see me at the door, waving good bye to him. As a housewife@retiree, ok lah I can do it. But actually not only that, he loves seeing me "doa" for him. How did he know that? Simple, he saw my lips moving like saying something when he reversed his car. But I told my husband earlier that it's not a spell or jampi. It's only a "doa" or prayer from his wife. He just said, " I know". 

The doa 

1. Bismillahillazi la yadurru ma'asmihi syaiun fil ardi wala fis samai wahuas sami'ul 'alim

2. A'uzubikalimatillahit tammati min syarrima kholaq.

3. Ya Allah Ya Hafiz Ya Muhaimin

And i also read it when my son was studying in Tahfiz school.
