Abu Hurairah reported,

"Any prayer in which the Opening of the Book is not recited is deficient." He repeated, "It is deficient. It is deficient."Abu Hurairah said, and before that he had said, "My beloved, peace and blessings be upon him, said," then he continued, "Persian, recite the Opening of the Book, for I heard the Messenger of Allah ﷺ say that Allah عز وجل said, 'I have divided the prayer between Myself and My servant'," and once he said, "'and My servant shall have what he asks for. When he says, "Praise be to Allah, Lord of all the worlds" [Fatihah 1:2], Allah says, 'My servant has praised Me.' When he says, "The Most Merciful, the Most Compassionate" [Fatihah 1:3], Allah says, 'My servant has glorified Me,' or 'My servant has extolled Me.' When he says, "Master of the Day of Judgment" [Fatihah 1:4], Allah says, 'My servant has entrusted his affair to Me.' When he says, "You alone we worship, and You alone we ask for help" [Fatihah 1:5], Allah says, 'This is between Me and My servant, and My servant shall have what he asks for'," and once he said, "'what he asked Me for.' Then His servant asks Him, "Guide us to the straight path, the path of those whom You have favored, not of those who have incurred wrath, nor of those who have gone astray" [Fatihah 1:6–7]. Allah says, 'This is for My servant. You shall have what you asked for'," and once he said, "'and My servant shall have what he asked Me for'."

حدثنا سفيان أخبرني العلاء بن عبد الرحمن بن يعقوب الحرقي في بيته على فراشه عن أبيه

عن أبي هرير

ة أيما صلاة لا يقرأ فيها بفاتحة الكتاب فهي خداج ثم هي خداج ثم هي خداج قال قال أبو هريرة وقال قبل ذلك حبيبي عليه الصلاة والسلام قال فقال يا فارسي اقرأ بفاتحة الكتاب فإني سمعت رسول الله ﷺ يقول قال الله عز وجل قسمت الصلاة بيني وبين عبدي وقال مرة لعبدي ما سأل فإذا قال {الحمد لله رب العالمين} قال حمدني عبدي فإذا قال {الرحمن الرحيم} قال مجدني عبدي أو أثنى علي عبدي فإذا قال {مالك يوم الدين} قال فوض إلي عبدي فإذا قال {إياك نعبد وإياك نستعين} قال فهذه بيني وبين عبدي ولعبدي ما سأل وقال مرة ما سألني فيسأله عبده {اهدنا الصراط المستقيم صراط الذين أنعمت عليهم غير المغضوب عليهم ولا الضالين} قال هذا لعبدي لك ما سألت وقال مرة ولعبدي ما سألني
