A number of our people have narrated from Ahmad ibn Muhammad from al-Husayn ibn Sa‘id from Fadalah from ‘Abdillah ibn Sinan from Abu ‘Abdillah (a.s.) who said, "Once my father took a major Ghusl (bath performed because of sexual relation or discharge of semen)." Someone said to him, "A spot is left on your back which water has not reached." He (the Imam) said to him, “It was not necessary for you (to inform me).

(I wish) you remained quiet.” He then wiped that spot with his hand.’” صحيح - Allamah Baqir al-Majlisi (Mirʾāt al-ʿUqūl fī Sharḥ Akhbār Āl al-Rasūl (3/138))
