I say, and with God's help: If your brothers were breastfed by your aunt, it is not permissible for you to uncover (see) your cousins. This is different if your cousins were breastfed by your mother; whoever among them was breastfed by your mother is considered a brother to you in breastfeeding, and it is permissible to uncover (see) him. If there is fitnah (temptation) in that, you should avoid it. And God knows best.
