The one who dies in a state of Wudhu is a martyr

The beloved Messenger of Allah şallAllāhu álayhi wa sallam said to Sayyidunā Anas rađiyAllāhu ánhu, 'Son! If you can spend all your time in a state of Wudhu then do so, because when the Angel of death captures the soul of a person in a state of Wudhu, he is written down as a martyr'.[1] 

Imam Ahmad Rida al-Qadri rađiyAllāhu ánhu states [from this hadîth we learn] that to remain in a state of Wudhu at all times is desirable.[2]

7 benefits of staying in a state of Wudhu at all times

The great Imam of Ahle Sunnah, Imam Ahmad Rida al-Qadri rađiyAllāhu ánhu says,

'Some A'rifīn (Gnostics) rađiyAllāhu ánhum have said that anyone who stays in a state of Wudhu at all times will be awarded 7 benefits by Allah Almighty:- 
(1) Angels will desire to be in his company
(2) The pen will constantly write virtuous deeds for him
(3) His limbs will praise Allah Almighty
(4) He will never miss his Takbīr Aula (first Takbīr of Salāh)
(5) When he sleeps Allah Almighty will send Angels to protect him from the evil of jinn and humans.
(6) He will die an easy death
(7) He will remain in the protection of Allah Almighty for as long as he is in this state.[1]
