"(If he is true in his claim) why are bracelets of gold not dropped upon him (from the sky), or why do there not come with him angels (to support him in his cause)?"
And then, why have no golden armlets been bestowed on him? Or why have no angels come along escorting him?" ('Aswirah' = Armlets of gold, which were considered a sign of honor, stature and royalty in many civilizations)
`(If he be a specially favoured one of God) why have not then bracelets of gold been bestowed on him (and thus a chiefdom conferred on him), or (rather why have no) angels accompanied him following him in procession formed in serried ranks?
Then (if he is a truthful Messenger,) why are the bracelets of gold not sent upon him, or why do the angels not come with him in ranks (in succession)?
“(If Moses is really as he claims to be) should there not have been placed upon him bracelets of gold or angels accompanying him?”
Al-muntakhab fi tafsir al-Qur'an al-Karim
" If only a bracelet of gold from heaven's realm has ornamented his arm to betoken authority or he has been companioned with the angels to confer on him dignity in an order of prophet hood!"
