Sayyiduna Mu'adh bin Jabal (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "You will remain under protection from your Lord as long as two kinds of heedlessness do not appear among you: the heedlessness of ignorance and the heedlessness of love of life. You will enjoin good, forbid evil and strive in the path of Allah; but when love of this world appears among you, you will not enjoin good, nor forbid evil, nor strive in the path of Allah. At that time, those who speak according to the Book and the Sunnah will be like 'the first forerunners' from the Muhajirun and the Ansar."
Al-Bazzar recorded it; its chain contains al-Hasan bin Bishr, whom Abu Hatim and others declared thiqah (trustworthy), and there is weakness in him.
