"So persevere in patience; for the Promise of Allah is true: and whether We show thee (in this life) some part of what We promise them, or We take thy soul (to Our Mercy) (before that), (in any case) it is to Us that they shall (all) return." --- The Holy Qur'an [40:77]
See you not how Allah coins a similitude: A good saying, as a good tree, its root set firm, its branches reaching into heaven, giving its fruit at every season by permission of its Lord? Allah coins the similes for humankind in order that they may reflect. And the parable of an evil word is that of a bad tree uprooted from the surface of the earth having no stability. --- The Holy Qur'an [14:24-26]
