Assalam u alikum Ustadh, Is it permissible to give charity in a masjid where you are buying food for someone or paying for another service (using a phone)? I heard it is not allowed to conduct business transactions in the masjid, so will this fall under buying/selling. Jazak Allahu Khairan

Ustadh AbdulAziz al-Haqqan

Giving sadaqah is allowed in the masjid even through applocations.
