Salam to all,
I used to think that the People who followed Noah into the Boat where only his Family,most christians ,jews and also think learn that Story,that the Person who were saved are :Noah (pbuh)
his wife
his sons (Ham,Sam,Japhet)
In the Quran we read that one son of Noah died in the flood and the wife of Noah was described as equal to Lots wife 66:10(maybe she died also in the flood)but there were other persons with them.
Sura 11
At length behold! There came Our Command, and the fountains of the earth gushed forth! We said: "Embark therein of each kind two, male and female, and your family except those against whom the Word has already gone forth and the Believers." But only a few believed with him. (40)
