Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) said: I once performed prayer at night with the Noble Prophet (peace and blessings of Allah be upon him). He stood for such a long time that a wrong thought occurred in my heart. We asked, "What was that wrong thought?" He replied, "I thought I should sit down and leave the company of the Noble Prophet (peace and blessings of Allah be upon him)."
