Kufw are fulfilled then preference should be given to a religiously devout man and we must totally ignore the attitude mentioned in this question. People who marry into sinful families might admire their choice from a material perspective but this choice is extremely harmful for the afterlife. A companion رَضِىَ اللهُ تَعَالٰی عَـنْهُ stated, ‘If someone married his daughter to an alcoholic, it is as though he threw her into fornication.’ The reason for this is that when an alcoholic is intoxicated, he divorces his wife many times and his wife becomes Ḥarām for him but he does not even notice it. (Tanbīĥ-ul-Ghāfilīn, pp. 81)

Question: Islam teaches that any white man is not better than any black man and vice versa, so then why is family lineage an important issue in the matter of Kufw?

Answer: When Islam says that no white man is better than any black man and vice versa, it means that the honour, lives and wealth of all Muslims must be protected without any discrimination and no one must be belittled in terms of respect and honour. Similarly all people are equal in following Allah’s and His Beloved Prophet’s commandments and no white man is better than any black man and vice versa in this matter. If a poor man commits a crime, he will get punished and if a rich man commits a crime he will also get punished; he cannot go unpunished. The Islamic philosophy referred to in this question is absolutely true and its true meaning has been elaborated. As for the question of considering lineage, occupation etc. in determining Kufw, it is Islam that has commanded this. The Revered and Renowned Prophet صَلَّى اللهُ تَعَالٰى عَلَيْهِ وَاٰلِهٖ وَسَلَّم said, ‘Do not marry your daughters except with Kufw.’

Sunan-ut-Tirmiżī states that Amīr-ul-Mu`minīn Maulā-e-Kāināt, lion of Allah کَـرَّمَ الـلّٰـهُ تَـعَالٰی وَجۡھَـهُ الۡـکَرِیۡم reported that the Greatest and Holiest
