Assalamualaikum wa rahmatullahi wa barakatuhu, on Quran.com, one can look up different Rub el Hizbs using the hyperlink e.g. https://quran.com/rub/48 for Rub el Hizb 48. https://quran.com/id/rub/45 leads to Rub el Hizb 45 in the Bahasa Indonesia language. Changing the number in the hyperlink e.g. https://quran.com/rub/48 to https://quran.com/rub/49 allows you to reach a specific Rub el Hizb. However, there is no webpage on Quran.com for a contents page of all of the Rub el Hizbs, where one could click on a label e.g. 'Rub el Hizb 2' and be directed to the webpage with the 2nd Rub el Hizb on it. Please kindly see Ayesha Nicole's comment on https://feedback.quran.com/feature-requests/p/juzhizb-no-should-feature-next-to-pg-no-when-scrolling-down , it includes an image with the Juz contents page. There is no equivalent for Rub el Hizbs. Please kindly set up a contents page for the Rub el Hizbs. Currently the options for navigation would be a) Google b) alter the hyperlink or c) press on the previous and next options on the bottom of the webpage. A contents page would help with this insha Allah. Jazakum Allahu Khayran.
