632. Narrated Nāfi': Once, in a cold night, Ibn 'Umar رضي الله عنهما pronounced the Adhān for the Ṣalāt (prayer) at Dajnān (the name of a mountain) and then said, "Offer Salat (prayer) at your homes", and informed us that Allāh's Messenger ﷺ used to tell the Mu'adh-dhīn to pronounce Adhān and say, "Ala Sallū fir-Rihāl [offer Ṣalāt (prayer) at your Ar-Rihāl (homes or camps)]" at the end of the Adhān on a rainy or a very cold night during the journey.
