With regard to the first question, and the second, as soon as you entered Islam you became one of the Muslims, with the same rights and duties as they have. Based on that, then you may strive to guard your chastity by marrying any good and righteous woman, based on the words of the Prophet (peace and blessings of Allaah be upon him) [regarding looking for a wife], “Look for the one who is religiously-committed, may your hands be rubbed with dust (i.e., may you prosper)!”

Narrated by al-Bukhaari, 5090; Muslim, 1466) – whether she is also new in Islam (i.e., a convert) or not. What matters is that she should be righteous, as I mentioned. 

Then if you propose marriage to a righteous woman, and she or her family do not agree, then you must be patient and continue looking, whilst also continuing to pray that Allaah will make it easy for you to find a righteous woman who can help you to obey your Lord. 

Secondly, with regard to the discrimination that you mention, Allaah says (interpretation of the meaning): 

“O mankind! We have created you from a male and a female, and made you into nations and tribes, that you may know one another. Verily, the most honourable of you with Allaah is that (believer) who has At-Taqwa [i.e. he is one of the Muttaqoon (the pious]”

[al-Hujuraat 49:13]

The Prophet (peace and blessings of Allaah be upon him) said: “O you who believe, verily your Lord is One, and your father [Adam] is one. There is no superiority of an Arab over a non-Arab or of a non-Arab over an Arab, or of a red man over a black man or of a black man over a red man, except in terms of taqwa (piety). Have I conveyed (the message)?” They said: “The Messenger of Allaah (peace and blessings of Allaah be upon him) has conveyed (the message).”

(Narrated by Ahmad, 5/411; classed as saheeh by al-Albaani in Ghaayat al-Maraam, 313; it was also narrated from Shaykh al-Islam Ibn Taymiyah that its isnaad is saheeh, in al-Iqtidaa’, 69). 

According to another hadeeth, the Prophet (peace and blessings of Allaah be upon him) said: “Those who boast about their forefathers should desist or they will be less significant before Allaah than the beetle that rolls up the dung with its nose. Allaah has taken away from you the arrogance of Jaahiliyyah and its pride in forefathers, so a person is either a pious believer or a doomed evildoer. All the people are the children of Adam and Adam was created from dust.” (Narrated by al-Tirmidhi, 3890; classed as hasan by al-Albaani in Saheeh Sunan al-Tirmidhi, no. 3100; and in Ghaayat al-Maraam, 312, it was said that al-Tirmidhi and Shaykh al-Islam Ibn Taymiyah classed it as saheeh). 

The dung beetle is a black bug that rolls up excrement. 

Hence it should become clear to you that Islam does not discriminate between one Muslim and another by any earthly standards, whether that be colour, lineage, wealth or country. Rather the only criterion by which people are regarded as superior to others before Allaah is taqwa (piety, consciousness of Allaah). Indeed, the sharee’ah commands the guardian of a woman, if a person comes to propose marriage who is religiously-committed and of good character and attitude, to hasten to arrange the marriage, and to beware of rejecting him and not accepting him, as the Prophet (peace and blessings of Allaah be upon him) said: “If there comes to you one with whose religious commitment and character you are pleased, then marry your daughter [or female relative under your care] to him, for if you do not do that then there will be much tribulation and mischief in the land.” They said, “O Messenger of Allaah, what if there is some other objection?” He said, “If there comes to you one with whose religious commitment and character you are pleased, then marry your daughter [or female relative under your care] to him,” three times.

 We ask Allaah to make it easy for you to marry a woman who will help you to obey your Lord.

 And Allaah knows best.
