===========================
A man came to Amir ul Muhmineen, 'Ali bn Abee Taalib Hasan Ibn Ali, 
May Allah be pleased with him and said,
===========================
"I will ask you four questions, so give me their answers":
===========================
01 -What is compulsory, and what is most compulsory?
===========================
02 -What is close-by, and what is most close-by?
===========================
03 -What is amazing, and what is most amazing?
===========================
04 -What is difficult, and what is most difficult?

The Amir ul-Mu'mineen answered:
===========================
01 -What is compulsory is Obeying and worshipping Allah, and what is most compulsory is Abandoning sins and disobedience to Allah!
===========================
02 -What is close-by is The Day of Judgement, and what is most close-by is DEATH!
===========================
03 -What is amazing is the Dunya, and what is most amazing is the love of the dunya!
