Yahya related to me from Malik from al-Ala ibn Abd ar-Rahman ibn Ya'qub that he heard Abu's-Sa'ib, the mawla of Hisham ibn Zuhra, say he had heard Abu Hurayra say, "I heard the Messenger of Allah, may Allah bless him and grant him peace, say, 'Whoever prays a prayer without reciting the umm al-Qur'an in it, his prayer is aborted, it is aborted, it is aborted, incomplete.' So I said, 'Abu Hurayra, sometimes I am behind the imam.'Hepulled my forearm and said, 'Recite it to yourself, O Persian, for I heard the Messenger of Allah, may Allah bless him and grant him peace, say that Allah the Blessed, the Exalted, said, "I have divided the prayer into two halves between me and my slave. One half of it is for Me and one half of it is for IVly slave, and My slave has what he asks." ' The Messenger of Allah, may Allah bless him and grant him peace, said, "Recite." The slave says, 'Praise be to AIIah, the Lord of theWorlds.' Allah the Blessed, the Exalted, says, 'My slave has praised Me.' The slave says, 'The Merciful, the Compassionate.' Allah says, 'My slave has spoken well of Me.' The slave says, 'Master of the Day of the Deen.' Allah says, 'My slave has glorified Me.' The slave says, 'You alone we worship and You alone we askforhelp.'Allahsays,'This ayat is between Me and My slave, and for My slave is what he asks. 'The slave says, 'Guide us in the straight Path, the Path of those whom You have blessed, not of those with whom You are angry, nor those who are in error. ' Allah says, 'These are for My slaves, and for my slave is what he asks . ' " ' "
