These are some of the examples of Muhammad's (S) and words as recorded in the Hadith literature.
1. O Allah! Improve my spiritual life, for that is to be my refuge;
And purify my material life, for I have to live it;
And prepare me for the life to which I shall have to return;
And keep me alive till it is good for me to be alive,
And call me back when it is good for me to die.
And lengthen my life in every goodly state,
And turn death into bliss before any evil state supervenes. (Hisn-al-Hisn)
2. The believer is not he who eats his full, while his neighbor is hungry.

He betrays a trust, lies, breaks promises, and when he quarrels, he commits excesses. (Bukhari)
7. Beware of envy, for envy devours good (deeds) like fire devours firewood. (Abu Dawud)

Do not vie with one another; do not envy one another,
Do not be angry with one another,
And be servants of Allah, brothers to one another, as you have been enjoined.
A Muslim is the brother of a Muslim - he does him no wrong, nor does he let him down; nor does he despise him. Fear of Allah is here, fear of Allah is here.
It is evil for a Muslim should look down on his brother.
For every Muslim is sacred to another - his blood, his honor and his property.
Allah does not look at your bodies, your forms, or your deeds, but he looks at your hearts. (Bukhari and Muslim)
9. Charity is due upon every limb of a human being on each day that the sun rises. To act justly between two (people) is charity. To help a man to his riding beast, or to load his provisions on it or lift them up for him is charity. A good word is charity. Every step going to prayer is charity. Removing from the road what causes harm is charity. (Bukhari, Muslim)
10. One, who strives to strengthen an oppressor and knows he is an oppressor, has already left Islam. (Bayhaqi)

15. Do you know backbiting?
They said, Allah and His messenger know best.'
He said, '(When) you speak about your brother, what he would dislike it is backbiting.'
Someone said, 'What if my brother is as I say?'
He said, 'If he is as you say, you have been backbiting; and if he is not as you say, you have slandered him.' (Muslim)
16. The Muslim who meets with people and endures any harm they may do, is better than he who does not meet with them and does not endure any harm they may do. (Tirmadhi)
