importance of sehri (Sahri); Benefits of fasting in islam

The Prophet [sallallaahu alaihi wa sallam] would eat Sehri:
In Ramadhan the Prophet [sallallaahu alaihi wa sallam] would eat Sehri and would declare it a blessed meal.
Syeduna Anas narrates:

“The Prophet [sallallaahu alaihi wa sallam] ordered me to bring him some food at the time ofsehri so I brought dates and water. He then ordered “See if there is anyone who will eat with me.” I called Zaid bin Thaabit who pleaded ‘Yaa Rasoolallah, I have already eaten and made theintention to fast.” The Prophet [sallallaahu alaihi wa sallam] replied “We too are going to fast” so he joined the Prophet [sallallaahu alaihi wa sallam] in sharing the Sahri.”
(Nisai)
It is narrated from Zaid bin Haarith [radi allah anho]:

“We would eat Sehri with the Prophet [sallallaahu alaihi wa sallam].”
Syeduna Aisha [radi allah anha] narrates that at Sehri the Prophet [sallallaahu alaihi wa sallam] would say:
“Bring us the blessed meal.”
