70,000 Angels every day visit at baytal ma’mur
Baitul Ma’mur is kaaba of heaven it is directly above the Ka’aba on earth. The angels make hajj to this House like we make hajj to Ka’aba. The Ka’aba on earth is a replica of it. In the 4th heaven, there is a river called Haywaan (River of Life).
Every single day a new group of 70,000 angels visit it. This will continue on until the Day of Resurrection. As soon as they perform salaah, they come out from the Bait-ul-ma’mur never to return there again,so theres always different 70,000 angels coming..
