Majma al-Zawaid — Hadith 3186

Abdullah bin Busr al-Hubrani narrates: I saw Sayyiduna Abdullah bin Busr (may Allah be pleased with him), the Companion of the Prophet (peace and blessings be upon him): when he had offered the Friday prayer, he would go out and make a round of the market, then come back to the mosque. He was asked: "Why do you do this?" He said: "I saw the leader of the Muslims doing it."
Imam al-Tabarani recorded it in al-Mu'jam al-Kabir; the narrator Abdullah al-Hubrani was declared da'if (weak) by Yahya al-Qattan and called thiqah (trustworthy) by Ibn Hibban.
