(As-Swaffaath) 37 : 77
وَجَعَلْنَا ذُرِّيَّتَهُ هُمُ الْبَاقِينَ
And We made his offspring the survivors.
“His offspring” mentioned in the verse does not mean only the offspring of Messenger Noah, but it includes the offspring of the believers who were saved in the ark with Noah. His wife and one of his sons were among the drowned. See explanation 11: 46-49; 71: 27-28.
