Using the empty space of a waqf property for performing Salaah
Q: A property had been made waqf with the intention that the income be utilised for various charity purposes. Presently there is a dire need for a at least a Musallah where the local Muslim brothers can offer daily 5 salaahs. The waaqif is willing to make a supplementary Deed to incorporate the establishment of a Musallah on the empty terrace of the building he had donated. Is this ok and can one perform Jummah salaah and also tarawih and Eid salaah in addition to the daily 5 times salaah in such a place?
