| Expenses [Text Block] | What were the Fund’s costs for the last year? (Based on a hypothetical $10,000 investment) Class Name Cost of a $10,000 Investment Cost Paid as a % of a $10,000 Investment Institutional Shares $96.73 0.90% |

| Factors Affecting Performance [Text Block] | How did the Fund perform over the last year? For the fiscal year ended May 31, 2024, the Amana Developing World Fund Institutional Shares returned 14.95%, ahead of the MSCI Emerging Markets Index, which returned 12.39%. For the five-year period ended May 31, 2024, the Institutional Shares reported an annualized return of 8.31%, the Index reported 3.54%, and the Fund’s Morningstar peer group reported 4.45%. Morningstar rated the Institutional Shares 4 Stars for overall performance. From the end of fiscal 2023 through the end of fiscal 2024, the Amana Developing World Fund's total net assets increased 49.7%. The Institutional Shares reported a turnover ratio of 1.3%, consistent with our overall strategy of investing in companies with long-term growth potential. Factors Affecting Past Performance Viewed alone, fiscal 2024 was a strong year for emerging markets. When compared to the US’s immense returns, driven by the rise in artificial intelligence (AI), emerging market returns look humbler. Developing economies experienced growth that propelled equities higher, despite a strong US dollar. While economic growth was strong, equity returns were quite divergent. For the one-year period ended March 31, 2024, India’s gross domestic product (GDP) grew 8.2% and the MSCI India Index returned 37.35%. Meanwhile, China’s GDP grew 5.4% but the MSCI China Index declined -16.98%. This divergence between economic gains and equity growth has been a consistent theme in emerging market investing; economic gains don’t necessarily accrue to shareholders. This, among others, is a key reason why we consider governance at both the company and geographic level. The above-mentioned disparity, and the fact that China constitutes 27.16% of the MSCI Emerging Markets Index, provides a compelling argument for active investing in emerging markets. Southeast Asia and Latin America benefited from supply chain diversification, Taiwan and South Korea are manufacturing leading-edge semiconductors, and India and Indonesia are adding masses to the middle class. With the MSCI Emerging Markets Index trading at 12.02x forward P/E versus 20.86x for the MSCI USA Index, we continue to see attractive value in developing world markets. |

| Factors Affecting Performance [Text Block] | How did the Fund perform over the last year? For the fiscal year ended May 31, 2024, the Institutional Shares of the Amana Growth Fund returned 26.34% (versus 7.09% last year). The Institutional Shares’ fiscal year performance trailed the broad S&P 500 Index, which gained 28.19%. While income is not an investment, the Institutional Shares paid a qualified income dividend at $0.24 per share. All Fund shareowners received a capital gain distribution of $0.35 per share. The Fund's total net assets increased 36.63% during the fiscal year. For the 10-year period ended May 31, 2024, the Institutional Shares provided an annualized return of 15.15%. Since their inception on September 25, 2013, the Institutional Shares provided an annualized return of 15.41%. What Factors Influenced Performance? After Nvidia’s May 2023 earnings announcement, the artificial intelligence (AI) frenzy took off, defining market performance ever since. The handful of stocks that dominated 2023 became known as the Magnificent Seven: Apple, Microsoft, Nvidia, Google, Amazon, Tesla, and Meta. All (except possibly Apple) are expected to be major AI players in the coming years. The Amana Growth Fund holds positions in Apple, Microsoft, Nvidia, and Google. We do not believe the other three stocks are appropriate holdings for the Fund. Those we do own are held in positions lower than their benchmark weights, creating a performance drag. Last year, GLP-1 drug companies Novo Nordisk and Eli Lilly helped overcome that drag, soaring to new heights on enthusiasm for the effectiveness of their weight loss drugs. Trane was a top contributor in the Industrial sector, benefiting from rising demand for cooling technologies. Looking Forward With a presidential election approaching, either bravery or foolishness would be required to opine on next year’s outlook. The two candidates have widely divergent opinions on a host of issues including taxation, tariffs, immigration, fossil fuels, alternative energy, and many others. Economic resilience (in terms of jobs and wages) adds to the uncertainty, defying the inverted yield curve prognostications, and consumers are still scarred from the pandemic-engendered period of high inflation. |

| Factors Affecting Performance [Text Block] | How did the Fund perform over the last year? For the fiscal year ended May 31, 2024, the Institutional Shares of the Amana Income Fund returned 20.05%, compared to 4.61% for the fiscal year ended May 31, 2023. The S&P 500 returned 28.19% over the 2024 fiscal year. As the Amana Income Fund’s objective is current income, the Institutional Shares distributed $0.32 per share at fiscal year-end. The Amana Income Fund Institutional Shares began operations on September 23, 2013. The Institutional Shares marked their 10-year anniversary during the fiscal year. For the 10-year period ended May 31, 2024, the Institutional Shares provided an average annual return of 9.97%. In comparison, the 10-year annualized return for the S&P 500 was 12.68%. Factors Affecting Past Performance Frenzied optimism over artificial intelligence (AI) drove much of the US and global stock market performance during the fiscal year. Broadcom and Taiwan Semiconductor, whose businesses were buoyed by demand for AI products and services, were among the top contributors to the Amana Income Fund’s performance. The two best performers in the Fund, however, were pharmaceutical company Eli Lilly (with a strong diabetes and emerging weight loss pipeline) and electrical components manufacturer Eaton Corp (whose products are used in power management and energy efficiency applications). The strong results from companies competing outside the AI arena illustrate the benefits of diversification, as their prospects are not set to dim even if the AI hype fades. Looking Forward Not only is 2024 a presidential election year in the US, but the UK will hold their national elections in July. The relationship between the US and China has grown increasingly adversarial on both a geopolitical and economic level. Global political uncertainty and the potential for ongoing escalation between the world’s two preeminent economic and military powers present investment risks. Meanwhile, the fast pace of innovation in AI, pharmaceutical development, and grid electrification offer investment opportunities. The Amana Income Fund will continue to prudently weigh risks and opportunities through ownership of companies with robust competitive advantages, skilled management, and strong balance sheets that position them well to deliver strong performance. |

| Factors Affecting Performance [Text Block] | How did the Fund perform over the last year? For the fiscal year ended May 31, 2024, the Institutional Shares of the Amana Participation Fund returned 2.26% and the FTSE IdealRatings Sukuk Index returned 2.69% . The Fund’s underperformance relative to the benchmark can be attributed to the Fund’s differing objective and prudent composition. At fiscal year-end, the Amana Participation Fund held 44 issues and reported an option-adjusted duration of 3.77 years. Last fiscal year-end, the Fund reported an option-adjusted duration of 4.94 years. In an interest rate environment marked by higher volatility on securities with longer maturities, the Fund’s duration profile was decreased to emphasize ownership of high-quality issuers and reduce duration risk.
