Remember when Abraham prayed: "O Lord, make this a city of peace, and preserve me and my progeny from worshipping idols: 35 My Lord! Lo! they have led many of mankind astray. But whoso followeth me, he verily is of me. And whoso disobeyeth me - Still Thou art Forgiving, Merciful. 36 "O our Lord! I have made some of my offspring to dwell in a valley without cultivation, by Thy Sacred House; in order, O our Lord, that they may establish regular Prayer: so fill the hearts of some among men with love towards them, and feed them with fruits: so that they may give thanks. 37 Our Lord! Lo! Thou knowest that which we hide and that which we proclaim. Nothing in the earth or in the heaven is hidden from Allah. 38 All praise be to God who bestowed on me Ishmael and Isaac in old age. Verily my Lord listens to prayer. 39 [hence,] O my Sustainer, cause me and [some] of my offspring to remain constant in prayer! "And O our Sustainer, accept this my prayer: 40 Our Lord! Forgive me and my parents and believers on the day when the account is cast. 41
