How much monthly alimony is due to each wife and her children to achieve justice, taking into account the number of wives and children and their needs, the existence of relatives who have rights of kinship and the rights of Allah, and the questioner's salary of 28,000 Riyals?

The maintenance of wives and children is obligatory to the extent of sufficiency, because it is enjoined due to need. It varies according to people's circumstances, their wealth or poverty, and the social environment in which they live. Therefore, you should spend on them from your means, in a reasonable manner, as Allah Almighty says: "Let a man of wealth spend from his wealth, and he whose provision is restricted - let him spend from what Allah has given him. Allah does not burden a soul beyond what He has given it."
