question #1 Sahih al-Bukhari 1429, Book 24, Hadith 32 : What is the significance of giving charity in Islam as mentioned in this narration?

I heard Allah’s Messenger (ﷺ) (p.b.u.h) while he was on the pulpit speaking about charity, to abstain from
asking others for some financial help and about begging others, saying, “The upper hand is better than
the lower hand. The upper hand is that of the giver and the lower (hand) is that of the beggar.”
