5. How can it be that the acceptance of all our deeds is conditional upon the acceptance of one action - our prayers?
When the police stop a driver on the road, they request the drivers licence from the driver. If the driver presents a doctor licence, political licence, builders licence, business approval documents and licence of “ijtihad”, or whichever other documents one can present, the police will not accept this from the driver. The only document the police will accept will be the drivers licence; otherwise, he will prevent the driver from proceeding.
In the Resurrection also, it is a condition that to be able to reach your destination, your Prayer Licence and required documents need to be with you and if not, none of the other documents or deeds you have will be accepted or give you salvation.
