THE DAILY ISLAMIC REMINDERS. YaumulJumuat. 13th day of Jumaadal Aakhir 1444AH (Friday 6th January. 2023). *_ETIQUETTES OF VISITING THE SICK_*. Bismillah. 
Visiting the sick does not involve only those whom you know, rather it is prescribed for those whom you know and those whom you do not know.
There is no sin in a man visiting a non-mahram woman, or a woman visiting a non-mahram man, so long as the following conditions are met: proper covering, no risk of fitnah, and no being alone together.
There is no sin in visiting a mushrik kaafir who is sick, if that serves an interest. The Prophet (peace and blessings of Allaah be upon him) visited a Jewish boy and called him to Islam, and he became Muslim. Narrated by al-Bukhaari (1356). And the Prophet (peace and blessings of Allaah be upon him) was present when his paternal uncle Abu Taalib was dying, and he called him to Islam but he refused. Agreed upon.
Du’aa’ should be made for the sick person in the manner narrated in the Sunnah: “La ba’s, tuhoor in sha ALLAAH (No worry, it is a purification, if ALLAH wills).” Narrated by al-Bukhaari.
It was narrated by Ahmad and Abu Dawood (3106) that the Prophet (peace and blessings of ALLAH be upon him) said: “Whoever visits a sick person who is not yet dying, and says seven times in his presence: ‘As’alu Allaaha rabb al-‘arsh il-‘azeem an yashfiyaka (I ask ALLAAH, Lord of the mighty Throne, to heal you), ALLAAH will heal him of that sickness in Shaa ALLAH.” Classed as saheeh by al-Albaani in Saheeh Abi Dawood.
The visitor should ask him how he is and how he is feeling, etc. That is proven from the Prophet (peace and blessings of Allaah be upon him), as narrated by al-Tirmidhi (983) and classed as hasan by al-Albaani. please remember today is Friday.
*_May ALLAH keep guiding us and heal our sick relatives_*. Aameen.
