Whatever is in the heavens and whatever is in the earth is Allah's; and whether you manifest what is in your minds or hide it, Allah will call you to account according to it; then He will forgive whom He pleases and chastise whom He pleases, and Allah has power over all things.
Al-Baqra Verse 284
The Prophet said, "The most hated person in the sight of Allah is the most quarrelsome person."
Sahih Bukhari: Volume 3, Book 43, Number 637
