Overall meaning :
Allah, Exalted be He, says: And mention, Muhammad, the story of Maryam (Mary), the daughter of ‘Imran, who guarded her chastity, keeping herself pure of all sexual contact all her life; so We sent Gabriel who breathed into the opening of her outer garment. The angel’s breath reached her womb, and she conceived Jesus without any husband, and so she and her son became a sign of Allah’ power and a lesson for people until the end of time.
The religion of all these prophets that you, people, must observe and adhere to is the same religion, namely Islam—which is showing total submission and obedience to Allah and worshipping none but Him—and I am your Lord and Creator; therefore, worship Me alone. People, however, disagreed and split up into different sects; they worshipped creation instead of the Creator and followed their whims. They will all be returned to Us, and We will judge them and repay them according to their deeds.
Therefore, whoever believes in Allah and His messengers, worships Allah alone and obeys His commands and does good deeds as much as possible will not be denied the reward for his endeavours, nor will they go to waste; rather, his reward will be multiplied many times over, and he will find all his actions written down in his record of deeds on the day he is resurrected after his death.
