Please reference these biblical obstacles.
this is a very broad topic. This link will help you see how capital punishment is understood:

i quote :
a person whose disposition is cruel should be
excluded from sitting in judgment in such cases (Sanhedrin 36B). Not only
should a person’s own record be pure and righteous, but his ancestry had to
be free of blemish before he could sit on this court (Sanhedrin 36B)
remind us of Jesus’ words, doesn’t it? he who is without sin, let him throw the first stone.
I quote:
Rabbi Simeon ben Shatach witnessed
the following incident: “I saw a man chasing another man into a ruin; I ran
after him and saw a sword in his hand dripping with the other’s blood, and
the murdered man in his death agony…” Even though he was convinced of the
man’s guilt, the rabbi could not testify against him, because he did not see
the actual crime (Sanhedrin 37b).
A person wrongfully flogged for robbery can heal. A person
improperly imprisoned for murder can be exonerated and set free. But someone
put to death for a crime he/she did not commit can never be redeemed. If we
are true to our faith and our tradition, we must respond to the imperative
of its teachings and do everything we can to keep our society from
committing the ultimate of injustices: the wrongful execution of an innocent
person.
reminds us of “Killing an innocent soul is like killing all of humanity” which means that if a court, for once, kills an innocent man, it is considered a murderous court.
I find it strange that you are deviating from the Christian understanding in light of Jesus’ teachings and even from the jewish understanding that reflects Jesus’ in order to support Muhammad’s stoning and cutting hands and tearing nails when in fact neither him nor his family history are sinless. Do you think if Muhammad was present when Jesus said who is sinless let him cast the first stone, do you think Muhammad would have thrown a stone? he would have put his head in the sand.
