When we arrived to Medina, the Messenger of Allah established a bond of brotherhood between me and Sa'd ibn Al-Rabi'. Sa'd ibn Al-Rabi' said: I am the wealthiest among the Ansar, so I will allocate half of my wealth to you. Also, see which of my wives you like, I will give [divorce] her to you, and when she becomes lawful [after waiting period], marry her. 'Abd-Ur-Rahman said: I have no need of that. Is there a marketplace where there is trading? Sa'd said: The market of Qeinuqa'. 'Abd-Ur-Rahman went to it next morning and brought some ghee and curd. Then he continued to go every morning. Then, it was not long before 'Abd-Ur-Rahman came back, and with traces of yellowness on him. The Messenger of Allah (PBUH) asked: Have you married? 'Abd-Ur-Rahman replied: Yes. The Messenger of Allah (PBUH) asked: And whom have you married? He replied: A woman from the Ansar? He asked: How much did you pay her? He said: The weight of a date seed of gold or a date seed of gold (5 dirhams). The Prophet (PBUH) said to him: Give a wedding feast, even if it is with a sheep.
If one of you is invited to a feast, let him attend it.
The Messenger of Allah (PBUH) commanded us to do seven things: attend funerals, visit the sick, bless one who sneezes, accept invitations, support the oppressed, fulfill oaths, and return greetings.
A man asked the Prophet (PBUH): Which deed is best? He said: To feed the poor and greet those you know and those you do not know.
