Al-Hasan bin Ayyub al-Hadrami narrates: Sayyiduna Abdullah bin Busr (may Allah be pleased with him) showed me a mole in the parting of his hair and told me that the Prophet (peace and blessings be upon him) had passed his blessed hand over it and had said: He will reach a century. The narrator says: Sayyiduna Abdullah (may Allah be pleased with him) used to comb his hair.
Al-Tabarani recorded it, and Ahmad recorded something similar. The narrators of Ahmad are the narrators of the Sahih, except al-Hasan bin Ayyub, who is thiqah (trustworthy); and the narrators of al-Tabarani are thiqat (trustworthy).
