Brothers turning into enemies

It is indeed sad to see brothers who were playmates,best friends and shared a good relationship in childhood to see them developing jealousy,hatredand negative emotions towards each other when they grow older.
And that too over insignificant,materialistic things. May Allah increase love among brothers,give them a big heart ,the ability to forgive and to have a sense of purpose and vision so that they dont get distracted by petty things. Ameen
