Arabic (Original)
حَدَّثَنَا خَلَفُ بْنُ الْوَلِيدِ حَدَّثَنَا ابْنُ الْمُبَارَكِ وَعَلِيُّ بْنُ إِسْحَاقَ أَخْبَرَنَا ابْنُ الْمُبَارَكِ عَنْ يَحْيَى بْنِ أَيُّوبَ عَنْ عُبَيْدِ اللَّهِ بْنِ زَحْرٍ عَنْ عَلِيِّ بْنِ يَزِيدَ عَنِ الْقَاسِمِ عَنْ أَبِي أُمَامَةَ عَنْ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ مِنْ تَمَامِ عِيَادَةِ الْمَرِيضِ أَنْ يَضَعَ أَحَدُكُمْ يَدَهُ عَلَى جَبْهَتِهِ أَوْ يَدِهِ فَيَسْأَلُهُ كَيْفَ هُوَ وَتَمَامُ تَحِيَّاتِكُمْ بَيْنَكُمْ الْمُصَافَحَةُ.
English Translation
Khalaf ibn al-Walid told us, Ibn al-Mubarak told us -- and Ali ibn Ishaq [said]: Ibn al-Mubarak informed us -- from Yahya ibn Ayyub, from Ubaydullah ibn Zahr, from Ali ibn Yazid, from al-Qasim, from Abu Umamah, from the Prophet, peace and blessings be upon him, who said: "Part of the completeness of visiting the sick is that one of you place his hand on his forehead or hand and ask him how he is; and the completeness of your greetings to one another is the handshake."
