- " لو يعلم الناس في الوحدة ما أعلم ما سار راكب بليل وحده (أبدا) ".
It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) said: "If people knew what (harm) there is in solitude, then no traveler would set out alone at night."
