(Ambiya') 21 : 76
وَنُوحًا إِذْ نَادَىٰ مِنْ قَبْلُ فَاسْتَجَبْنَا لَهُ فَنَجَّيْنَاهُ وَأَهْلَهُ مِنَ الْكَرْبِ الْعَظِيمِ
And to Noah, when he called Us before, then We responded to him and saved him and his family from the great misery.
Noah was the first Messenger who was given the first version of Adhikr as explained in verse 7: 59-64. But even after conveying the Message for about 950 years, only a few among his people believed. Even one of his sons and his wife didn’t become believers. Thus Lord drowned that transgressed people and saved Noah and believers in an ark as explained in verses 11: 36-44. Believers consider only believing men and women as his family, i.e. the single party of Lord who testifies Adhikr as explained in verse 11: 45-46. See explanation 9: 28 and 17: 3.
