[Taken from "Sitting during the blessed month of R
"Sahoor" with an "a" is the actual food eaten. "Suhoor" with a "u" is the act of eating the food.
A person should not leave the sahoor meal even if he does not feel like eating; he can have something very light, a small snack in order to implement the Sunnah.
-Shaik Salih al-fawzan: Buloogh al-Maram
" To shorten durood ( sallallahu-alaihi-wa sallam) to 'SAW' is a proof of one's laziness."
-Sh Muqbil Rahimahullah[ الاْ جوبة علي أسْلة العيزري]
"The first person to use symbol of ' ص ' for shortening ( Sallallahu-Alahi wa sallam), his hands were cut."
-Imam as-Suyuti rahimahullah [تدريب الراوي]
