Do the names Yaghooth and Nasra, mentioned in the Qur’an, indicate anything?

The names mentioned in Surat Nuh are the names of righteous men who lived among Noah's people. When they died, their people grieved for them, so Satan commanded them to make statues in their likenesses to remember them, but they did not worship them. In the time of their grandchildren, Satan inspired them that their ancestors used to worship these statues, so they worshipped them instead of Allah. The origin of this story was narrated by Al-Bukhari in his Sahih from Ibn Abbas, may Allah be pleased with both of them.
