question #1 Sahih al-Bukhari 2442, Book 46, Hadith 3 : What are the responsibilities of a Muslim towards their fellow Muslims in terms of oppression and support?

Allah’s Messenger (ﷺ) said, “A Muslim is a brother of another Muslim, so he should not oppress him, nor
should he hand him over to an oppressor. Whoever fulfilled the needs of his brother, Allah will fulfill
his needs; whoever brought his (Muslim) brother out of a discomfort, Allah will bring him out of the
discomforts of the Day of Resurrection, and whoever screened a Muslim, Allah will screen him on the
Day of Resurrection . ”
