It is narrated from Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) that when there is cheating in measure and weight, the rain will be withheld; when fornication becomes widespread, killing will increase and the plague will break out; and when lying becomes abundant, al-harj (chaos and killing) will increase. This hadith is sahih (authentic) on the condition of the two Shaykhs (Bukhari and Muslim), but they did not record it.
