Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) said: I heard the Messenger of Allah (peace and blessings be upon him) saying: "People are like a hundred camels among which there is hardly a single one fit for riding."
Ibn Shihab al-Zuhri (may Allah have mercy on him) said: Sayyiduna Umar (may Allah be pleased with him) used to say: O company of the Muhajirun, do not amass your wealth in Makkah; rather, keep it ready in the abode of your emigration, for a man's heart is with his wealth.
