It is narrated from Sayyiduna Hasan bin Ali (may Allah be pleased with them both) that he said: The Messenger of Allah (peace and blessings be upon him) taught me these words for the witr prayer: 'Allahumma-hdini fiman hadayt, wa barik li fima a'tayt, wa qini sharra ma qadayt, fa-innaka taqdi wa la yuqda 'alayk, wa innahu la yadhillu man walayt, tabarakta rabbana wa ta'alayt' (O Allah, guide me among those You have guided, bless me in what You have given, and protect me from the evil of what You have decreed. Indeed, You decree and none can decree against You, and the one whom You befriend is never humiliated. Blessed are You, our Lord, and Most High).
