2:221 Concept Of Wali
I think it has to do with language. Also, see this verse: وَإِذَا طَلَّقْتُمْ النِّسَاءَ فَبَلَغْنَ أَجَلَهُنَّ فَلَا تَعْضُلُوهُنَّ أَنْ يَنكِحْنَ أَزْوَاجَهُنَّ إِذَاتَرَاضَوْا بَيْنَهُمْ بِالْمَعْرُوفِ ذَلِكَ يُوعَظُ بِهِ مَنْ كَانَ مِنْكُمْ يُؤْمِنُ بِاللَّهِ وَالْيَوْمِ الْآخِرِ ذَلِكُمْ أَزْكَى لَكُمْ وَأَطْهَرُ وَاللَّهُ يَعْلَمُ وَأَنْتُمْ لَا تَعْلَمُونَ(2:232) “And when you have divorced your wives and they have reached the end of their waiting period, do not prevent them from marrying their future husbands if they have come to an agreement according to the norms [of decency] . These words of advice are given to every one of you who believes in Allah and the Last Day; this is more decent for you and more chaste. And [in reality] Allah knows, but you do not”. ( 2:232 )
