In the community there is a belief that every Friday night it is desirable to connect the husband and wife so that reward. Even with this assumption is then often used as humor every Friday night.
But assuming it's correct?
According to Shaykh Wahbah Zuhayli Az-there is no Sunnah which advocated sexual relations on certain nights. Includes Friday night. This is just a suggestion of a group of scholars. So it's not a direct Messenger of the word.
While according to Shariah consultation could prejudice that is circulating in the community at large based on the following Hadith. From Ibn Abi Aus Aus ' anhu, narrated that the Messenger of Allaah ' alaihi wa sallam said,
"Whoever taking a bath on Friday and to bathe, he left in the morning and get the early sermons, he runs and doesn't drive, he came closer to the priest, silent, as well as concentrate to listen to the sermon then every step his feet rated as a reward he will receive Yes r. "(Narrated by Ahmad and Ibn maajah Nasaa'i-, judged by priests; An-Nawawi and Shaykh Al-Albani)
Well there are some scholars who interpret "bath and bathe's" intimate relationship husband and wife. Because once touch, his wife had to bath junub.
If the above Hadith that so grip, then husband and wife relationships presumption every Friday night is the Sunnah of the Messenger who's been misguided. Because according to the Hadith should be morning Prayer before leaving Friday.
And Allah knows best.
