I am using a [dictionary of Syriac][1], which is close in meaning to Arabic. I could be mistaken. The letters around Magen David spell טפטף יה - make noise Hashem (plea), clatter, do not be silent. I.e. outside of the grave frighten the demons.

Insied the grave:

באב - for father

קבוֹל כסן - accept (with gratitude) the covered (likely several people)

כסאן כסאבן - a gift (sent in honor) at the time of their old age
