وَمَآ أَرْسَلْنَا مِن رَّسُولٍ إِلَّا بِلِسَانِ قَوْمِهِۦ لِيُبَيِّنَ لَهُمْ ۖ فَيُضِلُّ ٱللَّهُ مَن يَشَآءُ وَيَهْدِى مَن يَشَآءُ ۚ وَهُوَ ٱلْعَزِيزُ ٱلْحَكِيمُ
And We never sent a messenger save with the language of his folk, that he might make (the message) clear for them. Then Allah sendeth whom He will astray, and guideth whom He will. He is the Mighty, the Wise.

Chapter: Visiting or looking at women having foster suckling reltions
Narrated `Aisha:
My foster uncle came and asked permission (to enter) but I refused to admit him till I asked Allah's Apostle about that. He said, "He is your uncle, so allow him to come in." I said, "O Allah's Messenger (ﷺ)! I have been suckled by a woman and not by a man." Allah's Messenger (ﷺ) said, "He is your uncle, so let him enter upon you." And that happened after the order of Al-Hijab (compulsory veiling) was revealed. All things which become unlawful because of blood relations are unlawful because of the corresponding foster suckling relations.
