Ibn Majah

"The Muslim has six courtesies due from the Muslim: He should greet him with Salam when he meets him; he should accept his invitation if he invites him; he should answer [by Yarhamuk-Allah (may Allah have mercy on you)] to him if he sneezes (and says Al- Hamdulillah); he should visit him if he falls sick; he should follow his funeral if he dies; and he should love for him what he loves for himself."

"The Muslim has four things due from the Muslim: He should answer [by saying Yarhamuk-Allah (may Allah have mercy on you)] to him if he sneezes (and says Al-Hamdulillah); he should accept his invitation if he invites him; he should attend his funeral if he dies; and he should visit him if he falls sick."

"Five are the rights of the Muslim: Returning his greeting, accepting his invitation; attending his funeral; visiting the sich; and answering (saying Yarhamuk-Allah) to the one who sneezes, if he praises Allah (says Al-Hamdu Lillah)."

"The Messenger of Allah (ﷺ) came walking to visit me (when I was sick), as did Abu Bakr, when I was with Banu Salimah.

"The Prophet (ﷺ) did not visit any sick person until after three days."

"When you enter upon one who is sick, cheer him up and give him hope of a long life, for that does not change anything (of the Divine Decree), but it will cheer the heart of the one who is sick."

"What do you long for?" He said: "I long for wheat bread." The Prophet (ﷺ) said: "Whoever has any wheat bread, let him send it to his brother." Then the Prophet 9saw) said: "If any sick person among you longs for something, then feed him."

"The Prophet (ﷺ) entered upon a sick person to visit him. He said: "Do you long for anything? Do you long for Ka'k (a type of bread)?' He said: "Yes.' So they sent someone to bring some Ka'k for him."

"The Prophet (ﷺ) said to me: "When you enter upon one who is sick, tell him to pray for you, for his supplication is like the supplication of the angels.'"

"I heard the Messenger of Allah (ﷺ) say: "Whoever comes to his Muslim brother and visits him (when he is sick), he is walking among the harvest of Paradise until he sits down, and when he sits down he is covered with mercy. If it is morning, seventy thousand angels will send blessing upon him until evening, and if it is evening, seventy thousand angels will send blessing upon him until morning.'"
