Abdullah bin Busr showed me a mole on the top of his head. I placed my finger on it, and he said, "The Messenger of Allah ﷺ placed his finger on it and said, 'You shall surely live a full lifetime.'"Abu Abdullah said, He had thick locks of hair.
أراني عبد الله بن بسر شامة في قرنه، فوضعت إصبعي عليها فقال: وضع رسول الله ﷺ إصبعه عليها، ثم قال: لتبلغن قرنا، قال أبو عبد الله: وكان ذا جمة.
Imam Ahmad (17689) and Ibn Abu Asim in al-Ahad wal-Mathani (1343) both narrated it, through the route of Abu Abdullah al-Hasan bin Ayub al-Hadrami, who said, then he mentioned it. Its chain of transmission is hasan because of al-Hasan bin Ayub al-Hadrami, for he is hasan al-hadith.Hakim (4/500) and Bayhaqi in al-Dalail (6/503) narrated it through routes from Abdullah bin Busr with the same wording, and they added, "So he lived a hundred years."
