(Another chain) which is similar to the narration of Muhammad bin Rabi'ah (a narrator in no.1424) but he did not narrate it in Marfu' form.
The Prophet Muhammad ﷺ taught that mindfulness was essential for living an ethical life; he said “Beware! Whoever among you lives should beware!” He was emphasizing the need to be aware of one’s own behavior at all times, so that one could avoid any wrongdoings or mistakes which could lead to regret later on in life. Furthermore, he also taught that it was important to think before speaking; he said “Whoever believes in Allah and the Last Day should speak good or remain silent” This means that if something does not benefit oneself or others then it is better not to say anything at all rather than speaking ill or causing harm with one’s words.
