What is the ruling on giving to a beggar in the mosque, and the ruling on selling immediately after the Friday prayer to those who pray last and leave first, and the ruling on giving to women who beg at the doors of mosques?

It is permissible to ask and to give charity to a beggar in the mosque if he is among those eligible for charity, and if he does not harm anyone or disturb those praying. Otherwise, it is not permissible, because it would be cooperation in sin. Selling at the mosque gates and in its courtyard is forbidden during the second call to prayer on Friday, due to the Almighty's saying: (O YOU WHO HAVE BELIEVED, WHEN [THE ADHAN FOR] PRAYER IS CALLED ON FRIDAY, THEN PROCEED TO THE REMEMBRANCE OF ALLAH AND LEAVE TRADE. THAT IS BETTER FOR YOU, IF YOU ONLY KNEW). It is permissible after the prayer has been performed, due to the Almighty's saying: (AND WHEN THE PRAYER HAS BEEN CONCLUDED, DISPERSE THROUGH THE LAND AND SEEK FROM THE BOUNTY OF ALLAH AND REMEMBER ALLAH OFTEN THAT YOU MAY SUCCEED).
