Translation: One day it was mentioned in conversation that hell had seven gates and Paradise had eight. I began to consider why Paradise had an extra gate and immediately it was conveyed to me by God Almighty: These are seven principles of vice and seven of virtue but there is also a gate of divine mercy which is an addition to the gates of Paradise (Badr, Vol. II, No. 29, Aug. 7, 1903, p. 227)
