Warning: Don't take this seriously, just another in-jokes about married couples... :)
An Arab man placed a Hadith sign about "doing the right thing in the right way at the right time..." in their kitchen. Next day, his wife placed it in their bedroom.
Question: Why the Arab men are silent when they are making love?
Answer: Because they are biting their thobe (or kandoura).
The above in-jokes were told to me by my Arab✿
