question #3 Sahih al-Bukhari 4998, Book 66, Hadith 20 : What can be inferred about the importance of the Qur’an and I`tikaf from the practices of the Prophet Muhammad (ﷺ) in his final year?

Gabriel used to repeat the recitation of the Qur’an with the Prophet (ﷺ) once a year, but he repeated it
twice with him in the year he died. The Prophet (ﷺ) used to stay in I`tikaf for ten days every year (in the
month of Ramadan), but in the year of his death, he stayed in I`tikaf for twenty days.
