Self-tanner does not invalidate ablution. Ablution is a ritual cleansing process in Islam that involves washing specific parts of the body before prayer. Self-tanner is a cosmetic product that darkens the skin temporarily and does not create a barrier that prevents water from reaching the skin during ablution. As long as the skin is clean and water can reach it during the ablution process, self-tanner does not affect the validity of ablution. **

Burping does not invalidate the ablution (wudu) in Islam. A person can continue to pray even after burping. However, if something more than just air comes out during the burp, such as food or drink, then ablution would need to be renewed before praying. It is recommended to maintain good manners and etiquette during prayer, including trying to control burping if possible. **

No, wearing braces does not invalidate prayer. As long as one is able to perform the physical actions of prayer, such as bowing and prostrating, braces do not interfere with the validity of the prayer. It is important to maintain proper hygiene and cleanliness while wearing braces to ensure that one's prayer is performed in a state of cleanliness. **

In general, laughing does not invalidate the prayer as long as it is not excessive and disruptive. Islam encourages a balance between seriousness and joy in worship, and a light-hearted moment during prayer does not necessarily nullify it. However, if the laughter is intentional, excessive, or disrupts the focus and reverence of the prayer, then it may invalidate it. It is important to maintain a respectful and focused demeanor during prayer while also allowing for moments of joy and gratitude. **

It depends on the specific situation. If the mistake is unintentional and not within your control, then it does not invalidate your prayer. However, if the mistake is intentional or within your control, then it may invalidate your prayer. It is important to seek knowledge and guidance on the specific circumstances to ensure that your prayer is performed correctly. **

No, wearing braces does not invalidate the prayer. As long as the braces do not prevent the proper pronunciation of the words during prayer or hinder the movements required in the prayer, it is permissible to pray while wearing them. It is important to ensure that the braces do not cause discomfort or distract one from focusing on the prayer. **

Vaginal secretion does not invalidate the fast. The fast is only invalidated by actions such as eating, drinking, or intentional vomiting. Vaginal secretion is a natural bodily function and does not break the fast. It is important to maintain good personal hygiene during fasting to ensure comfort and cleanliness. **

Taking a shower does not invalidate wudu as long as the conditions for wudu are not broken during the shower. If the water reaches all parts of the body, including the required areas for wudu, and there is no breaking of wind, using the bathroom, or any other action that invalidates wudu, then the shower does not invalidate wudu. However, if any of these conditions are not met during the shower, then wudu would need to be performed again. **
