﴿ قَالَ لَهُم مُّوسَىٰٓ أَلْقُوا۟ مَآ أَنتُم مُّلْقُونَ ﴾

“[And] Moses said unto them: “Throw whatever you are going to throw!””

Moses said to them after they had said to him Either you cast or we shall be the casters Q. 7115 ‘Cast what you have to cast’ — the command to do this signifies an authorisation for them to cast and a means whereby the truth will be made to prevail.
