Remember when Abraham prayed: "O Lord, make this a city of peace, and preserve me and my progeny from worshipping idols: 35 My Lord, they have led so many men astray! Anyone who follows me is with me, but if anyone turns against me, You are surely forgiving and merciful. 36 O our Lord! surely I have settled a part of my offspring in a valley unproductive of fruit near Thy Sacred House, our Lord! that they may keep up prayer; therefore make the hearts of some people yearn towards them and provide them with fruits; haply they may be grateful: 37 "O our Lord! truly Thou dost know what we conceal and what we reveal: for nothing whatever is hidden from Allah, whether on earth or in heaven. 38 "Praise be to Allah, Who hath granted unto me in old age Isma'il and Isaac: for truly my Lord is He, the Hearer of Prayer! 39 Grant, O Lord, that I and my offspring may remain constant in devotion. Grant, O Lord, my supplication. 40 "Our Lord! Forgive me and my parents, and (all) the believers on the Day when the reckoning will be established." 41
