During all of Amir's past problems in both Afghanistan and California--his guilt over not helping Hassan when he is raped by Assef, his deceitful planting of gifts to make Hassan appear guilty, Baba's cancer, and even Soraya's inability to conceive a child--Amir has never asked Allah for help.

I haven't prayed for fifteen years. I have long forgotten the words.  (Chapter Twenty-Five)

Amir has followed Baba's belief that there is no God, but Amir now sees that "Baba was wrong." Sohrab's suicide attempt is the impetus for Amir to renew his faith, and he promises to worship Him daily, memorize the Koran, fast at Ramadan--all in the hope that God

... grants me this one wish: My hands are stained with Hassan's blood; I pray God doesn't let them get stained with the blood of his boy too.  (Chapter Twenty-Five)
