6:63Say, “Who delivers you from the darkness of land and sea?” You call upon Him humbly and inwardly: “If He delivers us from this, We will surely be among the thankful.”

6:67For every happening is a finality, and you will surely know.

6:99And it is He who sends down water from the sky. With it We produce vegetation of all kinds, from which We bring greenery, from which We produce grains in clusters. And palm-trees with hanging clusters, and vineyards, and olives, and pomegranates—similar and dissimilar. Watch their fruits as they grow and ripen. Surely in this are signs for people who believe.

6:139And they say, “What lies in the wombs of these animals is exclusively for our males, and prohibited to our wives.” But if it is stillborn, they can share in it. He will surely punish them for their allegations. He is Wise and Knowing.
