Why have my repeated and sincere prayers for sustenance and chastity not been answered? Is this evidence of God's wrath upon me?

A Muslim must be patient and content with Allah's decree, remembering Allah's wisdom and that good may lie in what a servant dislikes. Emphasis is placed on striving in supplication, with persistence and without haste or despair of a response, for Allah answers the supplicant, or diverts evil from him, or reserves reward for him; a Muslim will not be deprived of good from his supplication. And Allah is more merciful to His servant than a mother is to her child, and whoever relies on Allah, He is sufficient for him.
