Hadith 861
Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) narrates this statement of the Prophet Muhammad (peace and blessings be upon him): Whoever recites in the morning: "O Allah! Whatever blessing I or any of Your creation receives today is from You alone, You have no partner. All praise is for You and thanks is for You." The Prophet Muhammad (peace and blessings be upon him) said: That person has fulfilled the gratitude for that day.
