Does the rule "Certainty is not removed by doubt" bear the legal responsibility for imitating the Maliki school of thought, who say that divorce is binding by a mere thought, even though certainty is imitating the Shafi'i school of thought?

All of this is due to the effects of obsessive whispering (waswasa). The questioner has been advised to ignore it and turn away from it. If he continues in this state, he will put himself in hardship and difficulty. His issue is simpler than he imagines, and if he were free from waswasa, he would not have occupied himself with it. Furthermore, it falls under the two principles: "Certainty is not removed by doubt," and "The default is for what was to remain as it was." What is certain is that he follows the Shafi'i madhhab, so he should maintain this certainty and not pay attention to doubts. He should beware of extremism, over-exertion, and exaggeration, for the Messenger of Allah, peace and blessings be upon him, said: "The extremists are ruined."
