Imam Barzali asked his master, Shaykh Imam Gharibi. Then Shaykh Imam Gharibi recited the following luminous poem:
ناكح الكف بخسف يبلى # يأتى به يوم القيامة حبلى
"Having fun with your palms by jabbing them is dangerous, he will come on the Day of Judgment with an old pregnant palm."
The author of the book of Asy-Syamil says that the husband can not take the cock from the wife's vagina belonging to an independent woman without her permission. Nor should I remove the penis from my servant's vagina unless he has permission from his parents. Another opinion says, it should be permission of the servant sahaya itself, and different from the male slave. Imam Malik argued, that the legal drill revoked makruh absolutely. The wife is not allowed to ask her husband to remove the penis from her vagina and return it up to her husband.
