What do you do about a sixty-year-old woman who prays incorrectly and forgets what she was taught after you leave?

The woman's mistake in her prayer should be corrected to the best of one's ability, because teaching the ignorant is obligatory even if they do not ask, as some scholars have said, and it is the doctrine of Al-Ghazali and Al-Shadhili. Therefore, it is obligatory to guide her with gentle words and kindness, as this is more conducive to acceptance, and it is a form of cooperation in righteousness, piety, and sincere advice. It is also obligatory for the woman to learn the rulings of prayer and other individual obligations.
