Within the Muslim community, there are those who encourage Muslims to have a high number of children. I also read that "procreation in Islam is a sign of God's will and a large family is perceived as a blessing" in Blyth, E. Ruth Landau, eds. 2009. Faith and Fertility: Attitudes Towards Reproductive Practices in Different Religions from Ancient to Modern Times. Jessica Kingsley Publishers.
But what does the Quran say about the number of children a family should have? For instance, are there explicit verses in the Quran that, e.g., encourage families to have at least one or two children, that a large family is a blessing, that a family with children is positive in some sense, et cetera?
I am looking for a detailed and canonical answer.
