Sayyiduna Salamah bin al-Akwa' (may Allah be pleased with him) went to al-Hajjaj bin Yusuf, and he said: "O Ibn al-Akwa', you have turned back on your heels, becoming a Bedouin after the emigration." He said: "No, but the Messenger of Allah (peace and blessings be upon him) permitted me to live in the desert."
