question #1 Sahih al-Bukhari 2837, Book 56, Hadith 53 : What actions did the Prophet (ﷺ) take during the battle of Al-Ahzab that demonstrated his humility and dedication?

On the day (of the battle) of Al-Ahzab (i.e. clans) I saw the Prophet (ﷺ) carrying earth, and the earth was
covering the whiteness of his `Abdomen. And he was saying, “Without You (O Allah!) we would
have got no guidance, nor given in charity, nor prayed. So please bless us with tranquility and make
firm our feet when we meet our enemies.
Indeed (these) people have rebelled against (oppressed) us but never shall we yield if they try to bring
affliction upon us.”
