The hisn ul-muslim, seeking refuge section, some of the citations are wrong. For example section 128, the citations are wrong and does not match https://sunnah.com/hisn. There is also a typo of Fathul-BAri instead of Fathul-Bari in section 129. There may be more errors but I did not check in depth. I suggest to use the data from sunnah.com/hisn for the app as it is accurate alhamdulillah, and the english transliterations are better.

Jazak Allahu khair for your work, I appreciate you making the hisn ul-muslim application!
