Nowhere in the biography of the prophet  he is reported to have ordered the murder of children. Most amazingly, he considered  them better than the believers themselves, he always said “ children are born with pure hearts (born with natural disposition).

He also prohibited killing children during his wars with the polytheists.

Did the prophet tolerate killing women?

Nowhere in the authenticated books or biographies did the prophet ordered the murder of any women.

He forgave a Jewish woman who poisoned the food to kill him.

He ordered that no woman be killed even caught in the field of the battle.

He forgave the women who killed his dear uncle and cleft his belly aside, taking his liver out and eating it.

He rebuked his companions because he found a woman killed on the battle field.

•   Anti-Islam groups always cites false versions that all Muslims scholars, old and new,  consider them untrue , they base their rejection of these narrations on the basics of the science of hadith.
•   The Christian  missionaries always twist the meanings and interpolate words which are not originally part of the narrations. 
•   The Christian missionaries adulterate many narrations just to smear the pure image of the prophet.
•   Also note that many translation of the biography of the prophet is not honest, they all function as a method to degrade Islam.
•   If you want to evaluate Islam as a religion sent from God, read the authenticated Islamic sources.
•   Also note that they Quote the Shia resources which were authored to serve their “false” dogma.
