Mecca’s weather was hot and muggy. It did was not good for the children’s delicate nature and was not a favorable condition for a healthy upbringing. In the desert, the weather was nice, the water was sweet and clean, life was easy, and the climate was mild. Besides, some of the tribes that lived in the desert had a language and diction that was smooth and sharp. They maintained their nobility and practiced good conduct.

Based on this, the Qurayshi gentry and leading figures practiced the custom of handing their children over to the tribal women in the desert to be breastfed for a cost, so that their children could grow and be brought up under healthier conditions and to learn and speak a dialect of Arabic that was appropriate in its essential form. The child would remain with his/her wet nurse for 2-3 years, and sometimes even more. For this reason, many tribes that lived in the uplands/prairies, Sa’d bin Bakr’s tribe in particular, would have a caravan of women go to Mecca a few times a year in which the women would take the newly-born infants with them to their homeland for the purpose of nourishment.
