Many of those who build mosques make landscaped gardens on the waqf land around the mosque to make it look beautiful and to provide shade. Is this permissible?.
We put this question to Shaykh ‘Abd al-Rahmaan ibn Jibreen (may Allaah preserve him) and he answered:
If that does not take space away from the worshippers, and it is not spending money that was endowed to the mosque in a waqf, and that the mosque needs it or there are people who need it, then there is nothing wrong with that being an adornment to the mosque.
And Allaah knows best.
