There is a blessing in suhoor. The Prophet ﷺ said: “Have Suhoor, as indeed there is a blessing in it.” [Al-Bukhari and Muslim] and he ﷺ also said: "Allah and his angels definitely send salutations on those who eat Suhoor." [Ibn Hibban and At-Tabarani in Al-Awsat, hasan by Al-Albani].
Moreover, Suhoor is in a blessed time, the last third of the night, which is the best time to make dua and seek forgiveness.
