Is it obligatory to correct information mentioned in a lecture about jihad, which stated that the Messenger of Allah, may Allah’s prayers and peace be upon him, saying: "They are from them," applies to striking enemies with a trebuchet, whereas the correct context of the hadith is when children and women are accidentally hit during a night raid? And is the failure to correct this considered lying about the Messenger of Allah, may Allah’s prayers and peace be upon him, or concealing knowledge, or a sin?

It is permissible to use the Hadith of Sa'b ibn Jaththamah as evidence for the permissibility of setting up mangonels against the people of war, even if there are women and children among them, and that they are included in the ruling. The intention is not to permit their intentional killing, but if they are hit, their killing is permissible due to their intermingling.

It is also permissible to launch a night attack on disbelievers and to target them with mangonels and fire, and to cut off their water supply, even if this entails the destruction of women and children.

The questioner was incorrect in limiting permissibility to the case of bombardment with mangonels, but his use of the Hadith as evidence for this case is correct, even if he forgot the reason for the Hadith's narration. What happened to the questioner does not fall under the threat of lying about the Messenger, due to his lack of intent, and because the Messenger did indeed say the Hadith.
