Follow Prophet Muhammad's (ﷺ) teachings, Respect those who have passed away by praying for them

This hadith is about the Sunnah of praying over a dead person, which includes reciting Surat al-Fatihah. The narrator of this hadith is Talhah b. 'Abd Allah b. 'Awf who prayed over a dead person along with Ibn 'Abbas and he said that this was the Sunnah. This hadith teaches us to follow the teachings of Prophet Muhammad ﷺ and to recite Surat Al Fatihah when we pray for someone who has passed away as it was his sunnah to do so. It also teaches us to be respectful towards those who have passed away and not forget them in our prayers as they are no longer with us in physical form but still remain in our hearts forever through our prayers for them and remembrance of them in our daily lives.
