It has long been a custom in the Islamic world to compose collections of 40 Hadith (sayings and actions of the Prophet Muhammad) for believers to memorize. Thread for the the era of Covid.

The most famous perhaps that of the thirteenth century Shafi’i jurist al-Nawawi, which I use in teaching.

Collections of Prophetic traditions also exist for specific subjects or according to specific transmitters. And, separately, since the beginning of Covid, Muslim jurists the world over have been handing down legal opinions (fatwa/fatawa) on how best to respond.

Most recently, and the first such collection I have seen since the spread of Covid, the South African Shafi’i mufti Taha Karaan published a collection of hadith dealing with epidemics along with his own extensive comments.

The collection is fascinating for various reasons, both for the degree that it builds on premodern hadith commentaries and that which it presents a new synthesis of premodern views. If you’re interested in the premodern stuff, check out my book.
