Marwan bin Salim al-Muqaffa' says: I saw Sayyiduna Ibn Umar (may Allah be pleased with them both) grasping his beard in his fist and cutting off whatever exceeded the fist, and he said that when the Messenger of Allah (peace and blessings be upon him) broke his fast, he would recite this supplication: 'Dhahaba al-zama'u, wabtallat al-'uruqu, wa thabata al-ajru in sha' Allah' (The thirst has gone, the veins are moistened, and the reward is established, if Allah wills). This hadith is sahih on the condition of the two Shaykhs, since both al-Husayn bin Waqid and Marwan bin al-Muqaffa' have been used as evidence.
