question #1 Sahih al-Bukhari 666, Book 10, Hadith 60 : What considerations should be taken into account when deciding whether to attend congregational prayers during adverse weather conditions?

Once on a very cold and stormy night, Ibn `Umar pronounced the Adhan for the prayer and then said,
“Pray in your homes.” He (Ibn `Umar) added. “On very cold and rainy nights Allah’s Messenger (ﷺ) used to
order the Mu’adh-dhin to say, ‘Pray in your homes.’ ”
