Does the wind invalidate the ablution of one who forcibly prevents its exit, and what is the ruling on performing supererogatory prayers with this ablution, and will one be rewarded for reciting the Qur’an without ablution?

If the urge to pass wind is merely a whisper (waswasa), it is advisable to ignore it. If it is not waswasa, then the prayer of one who is suppressing the two 'foul things' (excrement and urine) or wind is valid according to the majority of scholars, but it is better to relieve oneself before prayer or recitation. It is disliked to perform prayer or recitation while suppressing the two 'foul things' or wind, unless there is a fear of the time expiring. If that is feared, one should pray in their current state, and their prayer is valid. Ablution is not invalidated merely by suppressing wind, but by its actual emission. Your prayer with this ablution is valid. Reciting the Quran does not require ritual purity from minor impurity (al-hadath (definition) al-asghar), but it is more complete for the reciter to be in a state of ablution. However, touching the Mushaf (definition) (copy of the Quran) requires complete purity.
