Abu Harun al-Abdi said: I saw Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him) with the hairs of his beard plucked out, so I asked: Do you play with your beard? He said: "No, this is what I suffered at the hands of the oppressors among the people of Syria. They burst into my house at the time of (the event of) al-Harrah and took whatever goods or valuables were in the house. Then another group came to me and found nothing in the house, and they were upset at leaving empty-handed." Then (one of them) said: "Lay the old man down." So they laid me down, and each one of them began pulling a lock out of my beard.
