Trump names Lt Gen HR McMaster as national security adviser

US President Donald Trump has named Lt Gen HR McMaster as his national security adviser.

He will replace Lt Gen Michael Flynn who was fired after just three weeks and three days in the job.

A lieutenant general with the US Army, HR McMaster served in Iraq and Afghanistan, where he worked on a government anti-corruption drive.

Mr Trump's first choice, retired Vice Admiral Robert Harward, turned down the role, citing "personal reasons".

Mr Trump has praised Herbert Raymond McMaster as "a man of tremendous talent and tremendous experience" who is "highly respected by everybody in the military".

Gen McMaster served in Afghanistan and Iraq, and is known as a thoughtful, if straight-talking, military strategist, the BBC's Aleem Maqbool reports from Washington.

What should a person do if he feels that his death is approaching?

Are there any signs before a person dies, whether he is a believer or a disbeliever? Are there any specific times for those signs? 
If it becomes apparent to him that his death is approaching, what should he do? When should we pay attention to these signs if there is such a thing? 
Is there any way to reduce the agonies of death? 
What are the best righteous deeds that one may be advised to adhere to?

Praise be to Allah.

Firstly: 

No one knows exactly when he will die, or in what land he will die. Allah, may He be exalted, says (interpretation of the meaning):

“Verily, Allah! With Him (Alone) is the knowledge of the Hour, He sends down the rain, and knows that which is in the wombs. No person knows what he will earn tomorrow, and no person knows in what land he will die. Verily, Allah is All-Knower, All-Aware (of things)”

[Luqmaan 31:34].

Secondly: 

There are no specific signs by which a person may know that his death and the end of his life are approaching. This is by the mercy of Allah towards His slaves, for if a person knew when he was going to die, and he knew that repentance expiates the sins that come before it, perhaps he might indulge in sins and commit evil deeds, and promise himself that one hour before his death he will repent and give up his sin. But such a person does not deserve to be a slave of Allah; rather he is a slave to his whims and desires.
