A man who knew there was a well around him, but he

Question : says: If he forgot that he was capable of using it and performed tayammum, he must repeat the prayer.

Answer : He forgot that he was capable of using it, meaning a person who knew beforehand that there was a well around him, yes, that there was a well around him, but he forgot. The day he prayed, he walked a little and walked, and he saw the well. He said, "O Allah, I am forgetful; I forgot this well." What should he do? He must repeat the prayer. He must repeat the prayer. How can he repeat the prayer when Allah the Exalted said: and we made a mistake?
They say that this is fulfilling a condition, and a condition is not dropped due to forgetfulness. So, in reality, you have a type of negligence. You did not remain thinking and estimating because you remember. However, merely saying, "By Allah, there is nothing around us," and then you remember and perform tayammum, this involves a type of negligence on your part. Therefore, you are required to repeat the prayer. It was also said that if he forgot that he was capable of using it, he does not repeat the prayer because he did not intend to disobey the command. When I prayed, the limit of my ability was to say, "There is no water around me." So I did not intend to disobey the command of Allah. Based on this, he does not have to repeat the prayer. But the more cautious course is to repeat it. The more cautious course is to repeat it. When the scholars say "the more cautious course," you should know they do not mean it is obligatory. Rather, they mean that scrupulousness requires repeating it so that a person does not expose himself to punishment. Here, they distinguish between the precautionary ruling and the definitive ruling. As the Shaykh al-Islam said in the Fatawa, he says: The precautionary ruling does not mean it is on the path of obligation, but on the path of scrupulousness by adhering to it.
