The Ruling on Complaining and Grieving at the Time of Calamity

Question:
If a calamity befalls a person, and he complains about this calamity or expresses dissatisfaction, does he sin for that?

Answer:
Yes, he sins for that. This is from the actions of the pre-Islamic age of ignorance (jahiliyyah). If he displays complaining and bad speech, this is from the actions of the pre-Islamic age of ignorance: wailing over the dead, tearing the chest, and slapping the cheeks. This is from the actions of the pre-Islamic age of ignorance. He should be patient and seek reward from Allah. It is permissible for him to cry over the dead; there is nothing wrong with that, as this is from mercy. The Prophet (peace and blessings be upon him) used to cry over the dead. However, if he raises his voice with panic, dissatisfaction, and cries of "woe and misery," or if he slaps his cheeks or tears his garment or chest, this is from the actions of the pre-Islamic age of ignorance. This is not permissible. Yes.
