I was commanded to take your allegiance and your pledge to accept what I brought from Allah, the Exalted, regarding 'Ali, the commander of the believers, and the Imams after him. O’ People! Ponder and understand the verses (of the Qur'an), observe those that are clear and do not follow those that are unclear; for by Allah no one can explain to you its limitations or clarify its meanings except the one whose hand I am holding (meaning Imam 'Ali).”
