[Machine] The kiss of a man to his wife and touching her with his hand without any barrier requires a person to perform ablution (wudu). This is the statement of Shaafi'ee. In the narration of Ibn Bukayr, it is stated that performing ablution is obligatory in this case. This is also the opinion of Umar, Abdullah bin Masood, and Abdullah bin Umar. However, Ibn Abbas disagreed with them and held the view that the mentioned touching in the Noble Quran does not require ablution, unlike the kiss.  

قُبْلَةُ الرَّجُلِ امْرَأَتَهُ وَجَسُّهَا بِيَدِهِ مِنَ الْمُلَامَسَةِ فَمَنْ قَبَّلَ امْرَأَتَهُ أَوْ جَسَّهَا بِيَدِهِ فَعَلَيْهِ الْوُضُوءُ لَفْظُ حَدِيثِ الشَّافِعِيِّ ؓ وَفِي رِوَايَةِ ابْنِ بُكَيْرٍ فَقَدْ وَجَبَ عَلَيْهِ الْوُضُوءُ فَهَذَا قَوْلُ عُمَرَ وَعَبْدِ اللهِ بْنِ مَسْعُودٍ وَعَبْدِ اللهِ بْنِ عُمَرَ وَخَالَفَهُمْ ابْنُ عَبَّاسٍ فَحَمَلَ الْمُلَامَسَةَ الْمَذْكُورَةَ فِي الْكِتَابِ الْعَزِيزِ عَلَى الْجِمَاعِ وَلَمْ يرَ فِي الْقُبْلَةِ وُضُوءًا
