All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.
Fist of all, before answering your question we say that it is clear from this question and some of your previous questions that you are affected with whispers about the subject of Kufr (disbelief).
Hence, we advise you to fear Allah and to stop giving in to these whispers and not to ask so many questions in general because asking so many questions is dispraised.
It is confirmed that the Prophet said: “Allah has hated for you (1) vain, useless talk, or that you talk too much about others, (2) to ask too many questions, (in disputed religious matters) and (3) to waste wealth (by extravagance).” [Al-Bukhaari]
We have so many important questions whose askers are waiting for an answer, so we cannot busy ourselves by the questions of those who are affected with whispers.
As for your question, there is no mockery or ridicule of religion in the word referred to in the question, and it was reported that there are birds of punishment in the fire –we seek refuge in Allah from that –al-Baghawi said in Ma’aalim at-Tanzeel:
“Ibn Mas’ood said: 'The souls of the family of Pharaoh will be in bodies of black birds, and they will be exposed to the fire twice every day; they go to and come from the fire; it shall be said to them, O family of Pharaoh! These are your places until the Hour is established.'” [End of quote]
Ibn al-Qayyim said in Zaad al-Ma'aad: “The souls of Pharaoh's family will be in the form of black birds and they enter the fire mornings and evenings.”
Allah knows best.
