Salam,
I revisited articles Iād seen about this topic, and as I skimmed through itās clear the majority view is thereās value to have international stocks aside from US large-cap multinationals. Warren Buffet is the only big name Iām aware of that doesnāt believe international stocks are worth holding.
There are many large portfolio managers that say international stocks are worth having. Hereās one:

Donāt I get enough international exposure with large U.S. multinationals?
āWhile U.S. Investors do get some foreign exposure from investing in U.S. multinationals, (generally defined as U.S.-based companies generating at least 25% of revenue outside the U.S.), in the sense that these companies profit from economic growth overseas, U.S. investors should hold non-U.S. stocks, for several reasons,ā says Abernethy.
U.S. multi-national companies tend to represent certain parts of global industry and not others. For example, by only owning U.S. multinationals investors will likely end up holding a lot of technology and healthcare firms. However, theyād be underrepresented in other important parts of the global economy, such as basic materials.
In addition, most U.S. multinationals fall in the Large Cap category, those companies with $10B or more in market capitalization. Our research has shown that the benefits of international diversification are greatest when investing in smaller companies, and that international small stocks helped to diversify equity portfolios of U.S. investors more than large stocks. U.S. multinationals provide little exposure to international equity from an investment return standpoint, even when a high percentage of revenue comes from foreign sales.
=======================
There are many others promoting having some exposure to non-US-based companies, e.g.:

=========================
Whatās unclear to me is whether the Islamic ETFs and mutual fund options capture enough of the diversification benefits or not. One of the above articles mentioned it was the smaller-cap international stocks that gave more benefit (less correlation with US stocks), and it doesnāt seem those are included in the funds that exist:
https://www.jhinvestments.com/fund-compare?compare=AMIDX,UMMA,SPWO
I like that SPWO has more funds and lower avg market cap than UMMA (from above, 325 vs 98 and 84 vs 125B), but it is pretty new so is missing the track record.
Amana developing world funds has only 42 stocks with avg market cap of $31B (per earlier article, lower is better). I suppose they could get lucky with their picks over the next decate but seems riskier as an actively managed fund, though the same fund managers (Scott Klimo and Monem Salam) have done a good job so far at that with the Amana growth fund that only has 36 holdings.
In any case, itās good to keep an eye out on their performance. The above website lets you see comparative growth of 10K with gains included over time.
