What is the ruling on killing locusts? And how do we reconcile the hadith: (Do not kill locusts), with the hadith: (Two dead things and two flowing bloods have been made lawful for us, the fish and the locust)?

The questioner: Is there a contradiction between his saying - peace and blessings be upon him - : , which is in "Sahih al-Jami' al-Saghir", and his saying - may Allah's prayer and peace be upon him - in the authentic hadith: - and he said - : , if there is a contradiction between them.

The Shaykh: What is the second hadith?

The questioner: , in his saying: , and the first hadith: Is this hadith in "Sahih al-Jami' al-Saghir"?

The Shaykh: First, it must always be noted that if two hadiths appear to some people to contradict each other, one must look closely at the point of contradiction. Currently, there is no contradiction between the two hadiths; that is because the first hadith: is an explicit prohibition against killing locusts, and the second hadith: , here there is no mention of so that it can be said: How do you reconcile "Do not kill" with "Kill"?!
So there is no contradiction! I say this as a first step in the way of removing the imagined contradiction, does not contradict his saying: , perhaps eating locusts is like eating dead fish, without being killed, without being hunted, so in that case there is no contradiction between these two hadiths; because the first explicitly states not to kill locusts, and the second permits eating locusts, but it does not explicitly state his saying - may Allah's prayer and peace be upon him - : Kill the locusts and eat them!
The contradiction is removed, but there remains a question that is not like the previous one - which was removing the contradiction between the two hadiths - ; for there is no contradiction. The question that arises, as they say today, is: Is it not permissible to kill locusts? The answer: As long as the hadith came as "Do not kill," that is the original ruling, and it is explicit in its indication that it is not permissible to kill them. But our Lord - Mighty and Majestic - says: , and there are many things among what Allah created, like ants - for example - that it is not permissible to kill them; because there is no benefit in killing them. But despite that, if the presence of some animals or insects results in harm that affects Muslims in their persons, in their wealth, in their crops; in that case, it is permissible to kill what causes harm in any of those matters we mentioned earlier. So his saying - peace and blessings be upon him and his family - : is the original ruling, but as happens in some years when tons of locusts invade the farms of Muslims, it is feared that these farms will become a harvest that Muslims will be harmed by, so it is permissible to kill the locusts - in this situation - to avert the harm. And this is the reconciliation between and what necessity requires, which is killing some animals that were prohibited from being killed, in order to remove the harm.
As for the hadith: and , there is no contradiction between the two matters for what we mentioned; that it is permissible to eat locusts, and they may have died of natural causes, so there is no killing. And despite that, if harm results for the farms; in that case, killing is permissible to avert the harm.
Yes.
