As-salamu 'alaykum wa rahmatullahi wa barakatuh, is having children mandatory to have in Islam? if a woman has a natural lack of desire not wanting to children, is she sinful? Jazak Allahu Khayran

Ustadh AbdulAziz al-Haqqan
It is forbidden for 1 spouse to deny the other spouse from children or more children unless there is an Islamic valid reason for it.
