Hadith 1800
'Ali (May Allah be pleased with him) said:
عن عليّ رضي الله عنه قال: حفظت عن رسول الله صلى الله عليه وسلم : "لا يتم بعد احتلام، ولا صمات يوم إلى الليل" . قال الخطابي في تفسير هذا الحديث: كان من نسك الجاهلية الصمات، فنهوا في الإسلام عن ذلك، وأمروا بالذكر والحديث بالخير.
I have retained in my memory the saying of the Messenger of Allah (ﷺ) that: "No one is considered an orphan after he has attained the age of maturity; and it is unlawful to remain silent from dawn till night." [Abu Dawud with Hasan (good) Isnad].
In plain words
The Prophet taught that no one is counted an orphan once grown, and that vowing total silence from dawn until night is not allowed. Faith is not shown by sealing the mouth.
