This was a great idea sent in by a mum:
“Avoid having everyone pray in their own little corner of the house, by designating one space of the home for this purpose. Make a prayer area an escape to a tranquil and peaceful place.”
Even if there isn’t enough space in the house for a prayer room, just having a common place to pray sets this up. And what’s more, it paves the way for praying in jamaat!
