Sayyiduna Hasan bin Ali (may Allah be pleased with him) said: The Messenger of Allah (peace and blessings be upon him) taught me a few words which I say in the qunut of the witr: "O Allah, guide me among those You have guided, grant me well-being among those You have granted well-being, take me as Your friend among those You have taken as friends, bless me in what You have given me, and protect me from the evil of what You have decreed; for indeed You decree and none can decree against You. The one whom You befriend is never humiliated, and the one whom You take as an enemy is never honoured. Blessed are You, our Lord, and Exalted."
