Sayyiduna al-Hasan bin Ali (may Allah be pleased with him) said that the Messenger of Allah (peace and blessings be upon him) taught me some words which I say in the qunut. Those words are: 'Allahumma-hdini fiman hadayt, wa 'afini fiman 'afayt, wa tawallani fiman tawallayt, wa barik li fima a'tayt, wa qini sharra ma qadayt, fa innaka taqdi wa la yuqda 'alayk, wa innahu la yadhillu man walayt, wa la ya'izzu man 'adayt, tabarakta Rabbana wa ta'alayt' "O Allah, guide me and include me among those whom You have blessed with right guidance; grant me well-being and include me among those whom You have granted well-being; include me among those whom You have taken as Your friends and make me Your friend; bless me in what You have given me; protect me and save me from the evil and harm You have decreed. Indeed, it is You who issues the decree, and no decree can be issued against You. Whoever You befriend can never be humiliated, and whoever You take as an enemy can never attain honour. Blessed are You, our Lord, and Exalted."
