  1. And the Jews will not be pleased with you, nor the Christians until you follow their religion. Say: Surely Allah's guidance, that is the (true) guidance. And if you follow their desires after the knowledge that has come to you, you shall have no guardian from Allah, nor any helper.

  2. He said: They are here on my track and I hastened on to Thee, my Lord, that Thou mightest be pleased.

  3. Bear then patiently what they say, and glorify your Lord by the praising of Him before the rising of the sun and before its setting, and during hours of the night do also glorify (Him) and during parts of the day, that you may be well pleased
