Is it true that the Prophets and Imams spent the whole night in worship? If so, how can we follow this example without negative effects on our health?
Bismillah
Thank you for your question. They (as) spent the whole of specific nights in worship, but slept in the night on a regular basis. Part of their night was always spent in prayer. A small amount of praying per night should not negatively effect most people's health.
May you always be successful
