Seek knowledge from reliable sources and understand religious teachings correctly .

This hadith is about how the people of Al-Kufah were discussing a verse from the Quran and Sa'eed bin Jabair went to Ibn 'Abbas to ask him for clarification. Ibn 'Abbas told him that this particular verse was revealed among the last of what was revealed in the Quran and nothing of it was abrogated after that. This hadith teaches us that we should always seek knowledge from reliable sources when we are unsure or confused about something related to our faith. We should also be aware that some verses in the Quran may have been abrogated by later revelations, so we must be careful when interpreting them.
