The remainder of the answer regarding the criterion for the qunut in times of calamity?

The Shaykh : What I see is that the matter should be left to the rulers. If they say, "Recite the qunut," we recite it. If they do not say it, we do not recite it, and there is no harm in a person making du'a between himself and Allah, for no one can prevent him. However, it is better not to recite the qunut publicly without the order of the rulers, lest people become disunited. Perhaps one person whose hen died would say, "This is a great calamity," and recite the qunut, just as one who comes to the imam says, "My mother has died, pray for her the prayer for the absent." His mother is just one of the people, yet he says, "My mother has died, O our imam, pray for her the prayer for the absent." There is no clear criterion in this, yes.
You seem to be surprised that a hen could be considered a calamity.
Abu 'Amir was a young boy in the time of the Prophet (peace and blessings be upon him). He had a small bird called al-Naghir with which he played. One day, the Prophet (peace and blessings be upon him) came in and found the boy sad because a calamity had befallen him: al-Naghir had died. So the Prophet (peace and blessings be upon him) used to say to him: Yes, come, come, my brother, right or left? Do you have a question? Good.
