According to Anas ibn Malik, when God's Messenger PBUH said,

'Help your brother, irrespective of whether he is the oppressor or the oppressed,'

a man said,

'O Messenger of God, I can help the oppressed, but how can I help the oppressor?'

The Prophet PBUH replied,

'Stop him from committing an act of oppression. That in iteself is a form of help.'

HADITH OF AL-BUKHARI AND MUSLIM

According to 'Abdullah ibn 'Umar, the Prophet PBUH, addressing the people on the occasion of farewell pilgrimage, exhorted them to listen carefully to what he had to say:

'All Muslims are brothers. They constitute one brotherhood. Nothing belonging to one Muslim can become legitimate property of another, unless it has been freely and willingly given. Do not, therefore, do injustice to your own selves. O God, have I conveyed your message? Woe betide you. When I am gone, do not become infidels and start killing each other.'

HADITH OF AL-BUKHARI

'Do not marry women for their beauty. It is possible that their beauty may destroy them. Do not marry women for their wealth. It is possible that their wealth may make them rebellious. Instead, marry them on the basis of their faith. And a black maid who is a believer is much better for you.'

HADITH OF IBN MAJAH

HADITH OF MUSLIM

BETTER TO FORGIVE THAN TO PUNISH

The Prophet Muhammad SAWS said: "It is better for a leader to make a mistake in forgiving than to make a mistake in punishing."

Al-Tirmidhi, Hadith 1011

'O young people, those among you who are able must enter into marriage. For it helps to divert your attention from women. And it is a safeguard against lust. And those who cannot marry should observe fasts, for fasting too is a safeguard.'
