What is the ruling on a second marriage for the purpose of procreation despite a difficult financial situation? Does this necessitate divorcing the first wife, or must the second wife be financially capable?

Marrying a second wife is permissible, whether the purpose is procreation or otherwise. It is better for someone who cannot marry a second wife but desires procreation to marry a woman capable of providing financially. If this is not possible, there is no harm in resorting to the other option (divorcing the first wife). However, it is preferable not to divorce the first wife and marry another, for Allah has guaranteed the sustenance of every soul, and marriage is a means of attracting sustenance. Allah Almighty says: "If they should be poor, Allah will enrich them from His bounty."
