[Machine] The Prophet ﷺ named Al-Hasan ibn Ali on his seventh day, and he derived the name Husayn from his name. It is mentioned that there was nothing between them except affection.
«أَنَّ النَّبِيَّ ﷺ سَمَّى الْحَسَنَ بْنَ عَلِيٍّ يَوْمَ سَابِعِهِ وَأَنَّهُ اشْتَقَّ مِنَ اسْمِهِ اسْمَ حُسَيْنٍ» وَذَكَرَ أَنَّهُ لَمْ يَكُنْ بَيْنَهُمَا إِلَّا الْحَبَلٌ
