question #3 Sahih al-Bukhari 7393, Book 97, Hadith 22 : How does the practice of reciting a supplication before sleep reflect one’s trust in Allah’s protection and forgiveness?

The Prophet (ﷺ) said, “When anyone of you goes to bed, he should dust it off thrice with the edge of his
garment, and say: Bismika Rabbi Wada`tu janbi, wa bika arfa’hu. In amsakta nafsi faghfir laha, wa in
arsaltaha fahfazha bima tahfaz bihi ‘ibadaka-s-salihin.”
