Al-Bara' ibn 'Azib said, "The Messenger of Allah, may Allah bless
him and grant him peace, instructed us to do seven things and forbade us
seven. He instructed us to visit the sick, to join funeral processions,
to bless people who sneeze, to fulfil our oaths, to help the wronged, to
return the greeting, and to accept invitations. He forbade us gold rings,
silver vessels, red (silk) saddle clothes, Qassi (silk and flax) garments,
thick brocade, embroidered silk, and pure silk."
Narrated Ibn Mas'ud reported that the Prophet, may Allah bless him and grant
him peace, said, "There are four things that one Muslim owes another Muslim:
to visit him when he is ill, to be with him when he dies, to accept when
he invites him, and to ask for mercy on him when he sneezes."
Abu Hurayra reported that the Messenger of Allah, may Allah bless
him and grant him peace, said, "A Muslim owes another Muslim six duties."
He was asked, "And what are they, Messenger of Allah?" He said, "To greet
him when he meets him, to accept when he gives him an invitation, to give
him good counsel when he asks for advice, to wish mercy on him when he
sneezes and says, 'Praise be to Allah,' to visit him when he is ill, and
to join the funeral procession when he dies."
'Abdu'r-Rahman ibn Ziyad ibn An'am al-Ifriqi said, "My father told
me that they were taking part in a sea raid in the time of Mu'awiya. He
said, 'Our ship was right up against the ship of Abu Ayyub al-Ansari. When
it was time for our midday meal, we invited him and he came over. He said,
"You invited me, but even though I am fasting, I cannot avoid accepting
your invitation because I heard the Messenger of Allah, may Allah bless
him and grant him peace, say, 'A Muslim owes six things to his brother.
If he neglects any of them, he has neglected an obligatory duty owed to
his brother. He should return his greeting when he greets him. He should
accept when he gives him an invitation. He should ask for mercy on him
when he sneezes. He should give him good counsel when he asks him for advice.'"'"
