You must know about yourself

                    Everyperson must know about yourself.

 You did not know yourself! You could not know ,what you are doing .
A Hadith of Rasul (SAW) says that , " Whosoever knows himself knows his Lord ."

Allah makes it clear in Surah 50 Al Qaf, verse16 that
"It was  We Who created man , and We know what dark  suggestions his soul makes to him : for We are nearer to him than his jugular vein ."
The Noble Quran describes this self in Surah 12 Yousuf , verse 53:
" Nor do I absolve my own self ( of blame ) : the (human) soul is certainly prone to evil , unless my Lord do bestow His Mercy : but surely my Lord is Oft forgiving , Most Merciful ."
The Glorious Quran in Surah 75 Al Qiyamah (The Resurrection) verse 2 describes nafs al Lawwama;
" And I do call to witness the self - reproaching spirit ."

Surah 13 Ar Ra' ad ( The Thunder ) , verse 28 confirms that :
  " Those who believe , and whose hearts find satisfaction in the remembrance of Allah . For without doubt in the remembrance of Allah do hearts find satisfaction ."
Allah ( S) asks the contented soul (the ruh) in the Noble Quran in Surah 7 Al Araf ( The Heights ) , verse 172:
" Am I not your Lord ( who cherishes and sustains you )?"- They said : " Yes! We do testify ! ( Alastu birabbikum; qaloo bala shahidna)

The Quran Al Kareem asserts in Sarah 43 AZ Zakhruf ( ornaments of Gold) , verse 14 :
"And verify, to our Lord We indeed are to return ! "
The following Surah 13 Ar Ra'ad ( The Thunder) , verse11 tells us how Allah (S) will expect our condition ;
  " Verily never will  Allah ( S) change the condition of a people until they change what is in their  hearts ."

Everyone thinked about yourself after that he want to be know about his around .
