Quran that demonstrates that a believer called a disbeliever a companion and a disbeliever called a believer a companion. As this is just to set forth how companionship has no relevance to positive or negative connotations
Cave:34
Disbeliever says
(Abundant) was the produce this man had: he said to his companion, in the course of a mutual argument: “more wealth have I than you, and more honour and power in (my following of) men.
Cave:37
Believer says:
His companion said to him, in the course of the argument with him: “Dost thou deny Him Who created thee out of dust, then out of a sperm-drop, then fashioned thee into a man?
As for the wives-we don’t curse them as we are not allowed but we must evaluate their actions. Surat Tahreem is important to read and understand because Allah emphasized on Aisha and Hafsa especially. “If you repent(Tatooba-grammatically refers to female duality-2 persons), for your heart have indeed inclined towards evil” Surat Tahreem:4. This verse also was discussed in Bukhari to be about Aisha and Hafsa.(unanimously agreed upon).
Allah swt the creator of the heavens of the earth alludes to Hafsas actions, divulging a secret from her own husband.
When the Prophet disclosed a matter in confidence to one of his consorts, and she then divulged it (to another), and Allah made it known to him, he confirmed part thereof and repudiated a part. Then when he told her thereof, she said, “Who told thee this? “He said, “He told me Who knows and is well-acquainted (with all things).”Tahreem:3
Volume 7, Book 63, Number 192:
Narrated ‘Ubaid bin ‘Umar:
I heard ‘Aisha saying, “The Prophet used to stay for a long while with Zanab bint Jahsh and drink honey at her house. So Hafsa and I decided that if the Prophet came to anyone of us, she should say him, “I detect the smell of Maghafir (a nasty smelling gum) in you. Have you eaten Maghafir?’ ” So the Prophet visited one of them and she said to him similarly. The Prophet said, “Never mind, I have taken some honey at the house of Zainab bint Jahsh, but I shall never drink of it anymore.” So there was revealed: ‘O Prophet ! Why do you ban (for you) that which Allah has made lawful for you . . . If you two (wives of Prophet) turn in repentance to Allah,’ (66.1-4) addressing Aisha and Hafsa. ‘When the Prophet disclosed a matter in confidence to some of his wives.’ (66.3) namely his saying: But I have taken some honey.”
Allah swt then set forth examples of two disbelieving wives, wife of Loot and wife of Nooh(a.s).
Allah sets forth, for an example to the Unbelievers, the wife of Noah and the wife of Lut: they were (respectively) under two of our righteous servants, but they were false to their (husbands), and they profited nothing before Allah on their account, but were told: “Enter ye the Fire along with (others) that enter!”
