“
I command you to fear God, say the truth, fulfill the pledges, give the deposits back to their possessors, avoid treason, show lenient wording, begin in greeting people, regard the neighbors, compassionate the orphans, work hard, neglect hopes, long for the life to come, worry about the Final Judgment, adhere to the faith, learn the Quran, suppress your rage, and behave with humility.
