One should not shorten his prayers on four occasions due to the Honorable the Exalted God’s Treasure. They are: the Honorable the Exalted God’s Shrine (the Ka’ba); the Shrine of God’s Prophet (MGB); the Shrine of the Commander of the Faithful Imam Ali (MGB), and the Shrine of Al-Hussein ibn Ali (MGB).”The compiler of the book - may God be pleased with him - said, “What is meant here is that one should not shorten his prayers in these holy shrines by the usual practice by intending to stay there for less than ten days for one who travels.”
