This is told as an example of the mercifulness of Muhammad.
Not what I'd call impressive.
In Christianity, God doesn't want your death. He wants your repentance. He wants you to regret and detest your wrongdoing, to confess your sin, to ask forgiveness, and to atone for the wrong you have done, so He can restore you in honor and grace and bring you to Himself.
These idiots revel it what they should wallow in.
And I have oft asked for forgiveness from my Maker for wishing death upon them but they persist in rubbing it in my face no matter how many times I turn the other cheek and showing the mothers mercy is not in the plan.
You can never atone for the wrong you have done. Only Christ can do that for you.
