This surah cautions us against being distracted by material things. One of the examples given is from the story of Musa (a). The Pharaoh asked why Musa (a) does not have gold bracelets or a procession of angels.
Discussion question: why did Pharaoh think Musa (a) should have gold bracelets? Did the agngels help Musa (a)? Could the Pharaoh see the angels that helped Musa (a)? When we can’t see something does that mean it isn’t there?
