"Sacrifice" according from the Qur'an and Words of the Prophet Muhammad

You will never attain to

virtue until you give in

alms what you dearly cherish.

God is aware of the alms you give.

(The Qur'an:Surah Ali-imran 3:92)

"What is the best Jihad?"

The Prophet was asked: 

"He who strives against his ownself

and his desires for the cause of Allah,"

said the Prophet.

Being weathly does not mean

having a great amount of property.

True wealth is self-contentment.

(Hadith of Bukhari)

One should never refuse

anything one is asked for.

(Hadith of Bukhari)

P/s : No leader can deliver the goods unless he is prepared to sacrifice some of the leisure time in the interest pf to quality performance. He should be content with what he possesses. This exemplary attitude will encourage teamwork among his associates.
