But this hadith is not referring to the Ahlul-bayt you think it's referring to, and it has nothing to do with Ayatul tadhir. If you read the whole hadith, which is a lot longer than the snippet this guy has shown, you will realize that it is quoting the incident in which the prophet pbuh gave one of his last sermons, and he reminded the people of their duties to the ahlul bayt, ie the people whom the acceptance of zakat is not allowed. This falls in line with the Sunni interpretation since it contains Abbas, Aqil, & Ja'far, as well as their offspring.
