The Cow - 2:239
If you are anxious and worried, (perform the prayer) on foot or on horseback. When you are safe, remember Allah as He taught you what you did not know.
Allah teaches by His Book what we do not know in the name of religion:
The Cow/2:128
Our Lord, make us both submissive to You (Muslims). And raise up from our progeny a people who submit to you. Show us how to worship You, and accept our turning to You, surely You are the Accepting, the Merciful.
The Cattle/6:91
"They did not appreciate Allah properly when they said: "Allah does not send down anything to any man". Say: "Who sent down the Book which Moses brought as a guidance and light for the people, which you wrote on paper to show them, but you concealed most of it. Through it you have learned what you and your fathers did not know?"Say: "Allah"and leave them in the error into which they have plunged, and let them play."
The Women/4:113
Had it not been for Allah´s grace and mercy upon you, a group of them would have led you astray. They can only mislead themselves; they can do you no harm. Allah sent down to you the Book and wisdom and taught you what you did not know. Allah´s favor towards you is great.
