I haven't done a comprehensive survey of all major religions, but I do have a fair number of Bible quotes saved up for moments like this:

Matthew 6:24 No one can serve two masters. Either you will hate the one and love the other, or you will be devoted to the one and despise the other. You cannot serve both God and money.

Leviticus 25:23 The land shall not be sold permanently, for the land is Mine; for you are strangers and sojourners with Me.

Ezekiel 16:49 Now this was the sin of your sister Sodom: She and her daughters were arrogant, overfed and unconcerned; they did not help the poor and needy.

James 5:1-6 Come now, you rich people, weep and wail for the miseries that are coming to you. Your riches have rotted, and your clothes are moth-eaten. Your gold and silver have rusted, and their rust will be evidence against you, and it will eat your flesh like fire. You have laid up treasure during the last days. Listen! The wages of the laborers who mowed your fields, which you kept back by fraud, cry out, and the cries of the harvesters have reached the ears of the Lord of hosts. You have lived on the earth in luxury and in pleasure; you have nourished your hearts in a day of slaughter. You have condemned and murdered the righteous one, who does not resist you.

Proverbs 14:31 Whoever oppresses the poor shows contempt for their Maker, but whoever is kind to the needy honors God.

Deuteronomy 15:7 If anyone is poor among your fellow Israelites in any of the towns of the land the Lord your God is giving you, do not be hardhearted or tightfisted toward them.

Luke 14:13-14 But when you give a banquet, invite the poor, the crippled, the lame, the blind, and you will be blessed. Although they cannot repay you, you will be repaid at the resurrection of the righteous.”

Matthew 6:19-21 Do not lay up for yourselves treasures on earth, where moth and rust destroy and where thieves break in and steal, but lay up for yourselves treasures in heaven, where neither moth nor rust destroys and where thieves do not break in and steal. For where your treasure is, there your heart will be also.

Leviticus 19:33-34 When a foreigner resides among you in your land, do not mistreat them. The foreigner residing among you must be treated as your native-born. Love them as yourself, for you were foreigners in Egypt. I am the Lord your God

Exodus 22:21 Do not mistreat or oppress a foreigner, for you were foreigners in Egypt.

Deuteronomy 10:19 And you are to love those who are foreigners, for you yourselves were foreigners in Egypt.

Deuteronomy 27:19 “Cursed is anyone who withholds justice from the foreigner, the fatherless or the widow.” Then all the people shall say, “Amen!”

1 John 4:20 If anyone says, "I love God," yet hates his brother, he is a liar. For anyone who does not love his brother, whom he has seen, cannot love God, whom he has not seen.
