A person in the early stages of his religious obligation was fasting a valid fast, but he was committing the secret habit, and he was completely ignorant that it invalidates the fast.

The questioner : He says: Noble Shaykh, a person in the early stages of his religious obligation was fasting a valid fast, but he was committing the secret habit, and he was completely ignorant that it invalidates the fast and that it necessitates the full ritual bath. So he would pray and fast and commit this habit. This was in the early stages of his religious obligation, and he was under fifteen years old. What is required of him after he learned the ruling and repented to Allah, given that he does not know the number of days on which he committed that habit, nor the number of prayers?

The Shaykh : There is a note on this question: "Before my religious obligation, he was expelling semen!" Is this expression correct? No. Because if semen comes out of him with pleasure, he has reached puberty, even if he is only ten years old. But we say the answer is: As long as he is doing it while fasting and he does not know that it is forbidden, his fast is valid, because we have mentioned that this is a rule. As for the prayers he was praying without performing the full ritual bath, while he did not know that that necessitates the bath, likewise: he is not required to make them up, because he was ignorant. For this reason, the Prophet (peace and blessings be upon him) did not require the man who was leaving the pillars of prayer to make up his previous prayers. Who was he? A man entered the mosque and prayed a prayer in which he did not settle, then he came and greeted the Prophet (peace and blessings be upon him), and the Messenger (peace and blessings be upon him and his family) said to him: So he went back and prayed as he had done before, and he came back, and the Messenger (may Allah's prayer and peace be upon him) made him repeat it three times, and he did not order him to make up his previous prayers, even though he said to him: So I say to this personThe questioner : You are not required to make up any prayers or any fasts, but I advise you to do many good deeds and to turn to Allah (Mighty and Majestic).
