The Ways of Ascent - 70:10 A friend does not ask about a friend.
On the Day of Resurrection, friendship and kinship will disappear between the disbelievers:
The Ornaments of Gold/43:67 On that Day close friends will be enemies to one another, except the righteous.

The Ways of Ascent/70:9 The mountains will be like discarded wool.
The Ways of Ascent/70:10 A friend does not ask about a friend.
The Ways of Ascent/70:11 They will be shown to one another. The guilty will want to give a ransom to escape the torment of that Day: His sons,
The Ways of Ascent/70:14 And everyone who is on the earth, that he may be saved.

He Frowned/80:34 On that Day a person will flee: from his brother,
He Frowned/80:37 On that Day everyone will have enough for himself.
