It is narrated from Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "How astonishing is the heedless person who is not being overlooked (in being seized and taken to account)! How astonishing is the seeker of this world while death is itself seeking him! And how astonishing is the one who laughs with a mouthful of laughter while he does not even know whether he has pleased Allah Almighty or angered Him!"
Takhrij and grading: Imam Abu Ya'la narrated this in his Musnad and Imam al-Bayhaqi in Shu'ab al-Iman; however, the hadith scholars have graded it da'if (weak) because of the presence of Yahya bin Ya'la al-Aslami in its chain.
