When you visit a sick or a dying person, you should utter good words
Umm Salamah (May Allah be pleased with her):
The Messenger of Allah (may the peace and blessings of Allah be upon him) said, "When you visit a sick or a dying person, you should utter good words because the angels say )Amin( at what you say.'' She added: When Abu Salamah (May Allah be pleased with him) died, I came to the Prophet (may the peace and blessings of Allah be upon him) and said: "O Messenger of Allah, Abu Salamah has died." He (may the peace and blessings of Allah be upon him) directed me to supplicate thus: "Allahummaghfir li wa lahu, wa a`qibni minhu `uqba hasanah [O Allah, forgive me and him, and bestow upon me a better future (give me a better substitute)]." So I supplicated as he directed, and Allah gave me a man who was better for me than Abu Salamah (i.e., the Prophet Muhammad (may the peace and blessings of Allah be upon him)). (The Prophet (may the peace and blessings of Allah be upon him) married Umm Salamah afterwards.)
[Muslim]
The Muslim presence with his Muslim brother when the latter is ill is considered a blessing on him and his family; he consoles his brother with his kind words, soothes his pain with his preaching, guidance, and humor. In addition to the other things that makes his patient brother happy, taking into account the general ethics prescribed by the Prophet – may the peace and blessings of Allah be upon him - and conveyed by his companions in words and deeds.
His presence at the time of death is an intercession for him; because he supplicates for the sake of his brother with what benefits him in his grave and the on the day of Resurrection.
There is nothing better for the sick and the dead than the supplications.
The Muslim should choose for himself and his brother the full and complete supplications, which is taken directly from the Qur'an and Sunnah.
The supplication should be in accordance with the patient's condition and need, and beneficial for the deceased in the Hereafter.
Rather, he should include in his supplication the family of the patient and the family of the deceased. He shall supplicate with what relieves their grief and sorrow, and help them to be satisfied with the decree of Allah.
That will surely brings them tranquility and tranquility, and promises them the good consequences and great reward for being patient and thanking their Lord.
