← Previous Hadith "The Messenger of Allah said to us: 'Your brother An-Najashi has died, so get up and offer the funeral prayer for him.' So we got up and formed row to pray for him, as rows are formed to pray for the dead, and he led us in praying for him as people pray for the dead."

Sunan an-Nasa'i Book 21, Hadith 158 Next Hadith → "The Janazah of a boy and a woman were brought. The boy was placed closer to the people and the woman was placed beyond him, and the funeral prayer was offered for them.
