This is an excerpt from one of Taqi Usmani’s works.
Anas b. Malik reported that Allah’s Apostle
saw the trace of yellowness on ‘Abd al-Rahman b. ‘Auf and said: What is this? Thereupon he said: Allah’s Messenger, I have married a woman for a date-stone’s weight of gold. He said: God bless you! Hold a wedding feast, even if only with a sheep. (Muslim 1427a)
Abdul-Rahman bin `Auf was one of the migrant Companions and he was a distant relative of Prophet
. Yet he did not invite the Prophet
to his marriage (Nikah) and hadn’t even told him about it. Only when Prophet
asked him, did he tell him that he got married.
On the other hand, the Prophet
didn’t complain why he hadn’t invited him to his marriage, and rather prayed for him to be blessed.
Marriage was conducted with such simplicity in those days that it didn’t occur to Abdul Rahman bin Auf to invite the Prophet
to his marriage.
Today if someone does not invite even casual acquaintances to their marriage they start complaining about not being invited but the Prophet
did not make any such complain.
