When a Muslim man gets married it’s obligatory on him to take care of his wife shelter,food and clothing. 100%
But then if he has more wives then also he should provide shelter,food and clothing to all. 💯.
But rather than that if he’s inclined to any one wife and gives her more like gifts then there is no harm on that. As long as he provides the basic needs of other wives.
All scholars and thoughts of school are on same page of this.
A man is allowed to marry two, three or four women due to the saying of Allāh:
فَانكِحُوا مَا طَابَ لَكُم مِّنَ النِّسَاءِ مَثْنَىٰ وَثُلَاثَ وَرُبَاعَ ۖ فَإِنْ خِفْتُمْ أَلَّا تَعْدِلُوا فَوَاحِدَةً
“So, marry other women of your choice, two or three, or four but if you fear that you shall not be able to deal justly with them, then marry only one…” An-Nisaa 4: 3
Shaikh Al-Fawzān stated: “So a man is able to marry a free single woman (if she agrees), and it is allowed for him to marry up to four. The benefits of polygamy are numerous both for the husband and his wives – and these benefits are not concealed from the person who has true insight, because if a man was restricted to just one woman whilst there are numerous women in a society, then many women will be deprived of husbands.” He continued: “Men have to take on the responsibility of maintenance and care over the women, whilst the women are looked after. So the woman is in an advantageous position because she is maintained, cared for, and is given a dwelling to live in as well as the fulfilment of passions. So this is to her advantage and benefit also, so she does not remain single, deprived of a (loving, caring and responsible) husband.”
Only men who are certain that they can treat all their wives fairly are allowed to marry more than one wife. That means, among other things, that they must be able to provide the same standard of housing, food and clothing for each wife, and treat each one with equal kindness and consideration as well as spending time with them equally. The Qur’an reminds men that to treat wives with justice is very hard; which (in reality) rules out polygamy for most men.
It is unfortunate that promiscuous sexual behaviour, fornication and adultery have become normal practices in many societies while plural Islamic marriage for men is outlawed; and people are indoctrinated (from an early age) into believing that polygyny is oppressive, demeaning to women and violates women’s rights (even if those women choose to be co-wives).
