@ Ukhti, I found this regarding compatibility in marriage. I can't quote you for some reason but inshaAllah you will see it.

Shaykh Muhammad ibn Saalih al-‘Uthaymeen (may Allaah have mercy on him) was also asked about a man who proposed marriage to another man’s daughter. When he asked about him, he found out that he did not pray, and the one who was asked about responded by saying: “Allaah may guide him.” Should they go ahead with this marriage?
He replied:
If the one who is proposing marriage does not pray in congregation, then he is an evildoer who is disobeying Allaah and His Messenger,
and going against the Muslim consensus, which is that offering prayer in congregation is one of the best of acts of worship.
Shaykh al-Islam Ibn Taymiyah (may Allaah have mercy on him) said in Majmoo’ al-Fataawa (23/222):
The scholars are agreed that it – praying in congregation – is one of the most important and best of acts of worship, and one of the greatest symbols of Islam. End quote.
But this evildoing does not put him beyond the pale of Islam, so it is permissible for him to marry a Muslim woman,
but someone else who adheres to Islam and is of an upright character would be better than him,
even if he is less wealthy and of a lesser lineage, as it says in the hadeeth:
“If there comes to you one with whose character and religious commitment you are pleased, then give (your daughter or female relative under your care) to him in marriage.”
They said: “O Messenger of Allaah, even if he falls short with regard to wealth and compatibility.”
He said: “If there comes to you one with whose character and religious commitment you are pleased, then give (your daughter or female relative under your care) to him in marriage” three times.
Narrated by al-Tirmidhi.
And it is proven in al-Saheehayn and elsewhere from the hadeeth of Abu Hurayrah that the Prophet (peace and blessings of Allaah be upon him) said:
“Women may be married for four things: their wealth, their lineage, their beauty and their religious commitment.
Choose the one who is religiously-committed, may your hands be rubbed with dust (may your prosper).”
These two ahaadeeth indicate that the best things to pay attention to are religious commitment and good character in both the man and the woman.
The guardian who fears Allaah and understands his responsibility is to pay attention to the advice of the Prophet (peace and blessings of Allaah be upon him,
because he will be asked about that on the Day of Resurrection.
