Does a woman offering herself to a righteous man contradict patiently enduring God's decree concerning delayed marriage, and how can a woman verify the righteousness of a man she has only heard about?

A woman offering herself for marriage to a righteous man does not contradict patience with Allah's decree. Taking the means (أخذ الأسباب) does not conflict with patience and contentment with destiny; in fact, it is part of Allah's destiny. The righteousness of a man can be known by strong presumption based on his outward appearance, and this can be confirmed by asking trustworthy relatives, colleagues, and neighbors.
