Pray when one remembers even if one has forgotten or missed their witr prayer.

This hadith teaches us that if we forget to pray the witr prayer or miss it due to oversleeping, we should still make sure to pray when we remember. This is an important lesson for Muslims as prayer is a fundamental part of our faith. We must make sure that even if we forget or miss a prayer due to any reason, we should still take the time out of our day and offer it as soon as possible. The Prophet Muhammad also taught us that Allah will forgive us for any mistakes made in our prayers if done with sincerity and humility.
