Missing davening due to business

Hi,

One who missed davening [prayer] due to business should recite the next amidah twice; he is not viewed as having been careless. This is true even if there had been time to pray earlier in the day, and it was only at the end that he became embroiled in his work and he missed the time to pray.

Of course, one should make sure to pray early in the acceptable timeframe if he anticipates that such a circumstance might arise.
