Quran 2:110 — The Heifer (Al-Baqarah)

You shall observe the Contact Prayers (Salat) and give the obligatory charity (Zakat). Any good you send forth on behalf of your souls, you will find it at GOD. GOD is seer of everything you do.

[2:109] Many followers of the scripture would rather see you revert to disbelief, now that you have believed. This is due to jealousy on their part, after the truth has become evident to them. You shall pardon them, and leave them alone, until GOD issues His judgment. GOD is Omnipotent.

[2:111] Some have said, "No one will enter Paradise except Jews or Christians!" Such is their wishful thinking. Say, "Show us your proof, if you are right."
