Does a mother doubt her purity when she smells her hand after cleaning it, performing ablution, and praying, and does that invalidate her prayer and ablution?

Islam is a religion of purity. It has mandated the removal of impurities and made ritual purity a condition for the validity of prayer. Impurities are purified by the removal of their substance and characteristics with water. However, the religion has made things easy for people. Most scholars have stated that the persistence of the color or odor of an impurity, after making an effort to remove them, does not cause harm. If only the odor remains and its removal is difficult, the correct view among the majority of scholars is that the ruling is one of purity. Therefore, the woman's prayer is valid after she has made an effort to remove the odor of the impurity, and she is not obliged to wash her hand again or repeat her ablution.
