Translation of the verse 19 from Surah Al-Ma’idah : Number of verses 120 - - page 111 - Part 6.
O people of the Scripture (Jews and Christians)! Now has come to you Our Messenger (Muhammad SAW) making (things) clear unto you, after a break in (the series of) Messengers, lest you say: "There came unto us no bringer of glad tidings and no warner." But now has come unto you a bringer of glad tidings and a warner. And Allah is Able to do all things.
O People of the Scripture, there has come to you Our Messenger to make clear to you [the religion] after a period [of suspension] of messengers, lest you say, "There came not to us any bringer of good tidings or a warner." But there has come to you a bringer of good tidings and a warner. And Allah is over all things competent.
(5:19) People of the Book! After a long interlude during which no Messengers have appeared there has come to you Our Messenger to elucidate the teaching of the true faith lest you say: 'No bearer of glad tidings and no warner has come to us.' For now there indeed has come to you a bearer of glad tidings and a warner, Allah is All-Power-ful. *41
*41). In the present context this sentence is extremely eloquent and subtle. It signifies that the same God who had sent warners and bearers of glad tidings to men in the past has now sent Muhammad (peace be on him) with the same task. At the same time it also means that they {should not treat the message of this warner and bearer of glad tidings lightly. They should bear in mind that if they disregard the injunctions of God, He can chastise them as He wills, for He is All-Powerful and All-Mighty.
