27:12 And put your hand into the opening of your garment [at the breast]; it will come out white without disease. [These are] among the nine signs [you will take] to Pharaoh and his people. Indeed, they have been a people defiantly disobedient."

And put your hand in the opening of your shirt; it will come out after entering it white like snow without being due to leprosy, as part of nine signs which testify to your truthfulness.
Along with the hand, they are: the staff, famine, loss of fruits, floods, locusts, lice, frogs, and blood, towards Pharaoh and his people.
They were a people left the obedience of Allah by disbelieving in him.

"And put your hand into your bosom, it will come forth white without hurt. (These are) among the nine signs (you will take) to Fir'aun (Pharaoh) and his people, they are a people who are the Fasiqun (rebellious, disobedient to Allah).
