Remember when Abraham prayed: "O Lord, make this a city of peace, and preserve me and my progeny from worshipping idols: 35 "O my Lord! they have indeed led astray many among mankind; He then who follows my (ways) is of me, and he that disobeys me,- but Thou art indeed Oft-forgiving, Most Merciful. 36 "O our Sustainer! Behold, I have settled some of my offspring in a valley in which there is no arable land, close to Thy sanctified Temple, so that, O our Sustainer, they might devote themselves to prayer: cause Thou, therefore, people's hearts to incline towards them and grant them fruitful sustenance, so that they might have cause to be grateful. 37 "O our Lord! Certainly, You know what we conceal and what we reveal. Nothing on the earth or in the heaven is hidden from Allah. 38 "All the praises and thanks be to Allah, Who has given me in old age Isma'il (Ishmael) and Ishaque (Isaac). Verily! My Lord is indeed the All-Hearer of invocations. 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 the believers on the Day whereon will be set up the reckoning. 41
