The Prophet Muhammad (SAW) said, "No one of you becomes a true believer until he likes for his brother what he likes for himself." - Bukhari, Muslim

Imagine a world where this hadith was followed. We live in a world filled with distasteful competition and hate; one in which people wish for the downfall of another. Very few people are genuinely happy at the success of their neighbor. The neglect of this advice from the Prophet (SAW) has led to cheating, bribery, dishonesty amongst members of the society.

The Messenger of Allah (SAW) said: "A man set out to visit his fellow brother in another town and Allah sent an angel on his way. When the man met the angel, the latter asked him, 'Where do you intend to go?'. He said, 'I intend to visit my brother in this town.' The angel asked, 'Have you done any favor to him that you intend to collect (a loan)?'. He said, 'No, I have no desire except to visit him becauseI love him for the sake of Allah, the Exalted.' Thereupon the angel said, 'I am a messenger to you from Allah (to inform you) that Allah loves you as you love him (for His sake).'" - Muslim

There is immense benefit in visiting fellow muslims for the sake of Allah. The bond of brotherhood in Islam is said to be even stronger than that of blood relations and whoever loves someone for the sake of Allah, Allah will return the love to him in a manner that suits Him.
