This portion of Al-Kitab takes its name from its author, Prophet Malachi (pbuh). He lived at a time when the rebuilding of the Holy House in Jerusalem had been long ago completed and the services of worship were happening on a regular basis. As time passed, Bani-Israel began to depart from Allah once again. The spiritual problems mentioned in this scripture are the same ones noted in Nehemiah: intermarriage with disbelievers, improper use of money, failure to give towards the work of Allah, and an attitude of rejection of spiritual things. After Prophet Malachi (pbuh), about 400 years pass in the history of Bani-Israel before another prophet appears. For more information, see Luke chapters 1 to 3 in the holy Injil.
