What is the ruling on being annoyed with one's parents and ridiculing them if they order one to sleep or wake up early, and ridiculing restaurants that close early? Is that considered ridiculing the Sunnah of early sleep?

The aforementioned distress is not mockery of the Sunnah. The cure for obsessive thoughts (waswas) is to completely disregard them, supplicate frequently, and occupy oneself with beneficial knowledge, righteous deeds, community service, or permissible sports. One should also avoid isolation, keep good company, seek refuge in Allah from Satan, and rely on Him, as Allah Almighty says: "Indeed, there is no authority for him over those who have believed and who rely upon their Lord" (An-Nahl: 99). Thus, the path to safety from his evil is to seek refuge in Allah and rely on Him, and to be adorned with faith and trust.

It is forbidden to mock parents, and one must avoid any word or action that harms them. Allah has commanded that they be addressed with respect, gentleness, and humility, and has forbidden scolding them or speaking harshly to them, as Allah Almighty says: "So do not say to them, 'Uff,' and do not repel them but speak to them a noble word. And lower to them the wing of humility out of mercy and say, 'My Lord, have mercy upon them as they nurtured me when I was small'" (Al-Isra: 23-24). The meaning of "Uff" is not to express exasperation at anything from them, and to be patient with them; and the meaning of "a noble word" is a soft, gentle word, like the words of a sinful servant to a harsh master.
