[Machine] I heard the Prophet’s muadhin (caller to prayer) on a cold night while I was under my blanket, and I wished for him to say "Pray in your homes". When he reached the part of the adhan that says "Hayya ‘ala al-falah" (come to success), he instead said "Pray in your homes". Then I asked about it, and it turns out that the Prophet ﷺ had commanded him to say that.
سَمِعْتُ مُؤَذِّنَ النَّبِيِّ ﷺ فِي لَيْلَةٍ بَارِدَةٍ وَأَنَا فِي لِحَافِي فَتَمَنَّيْتُ أَنْ يَقُولَ صَلُّوا فِي رِحَالِكُمْ فَلَمَّا بَلَغَ حَيَّ عَلَى الْفَلَاحِ قَالَ صَلُّوا فِي رِحَالِكُمْ ثُمَّ سَأَلْتُ عَنْهَا فَإِذَا النَّبِيُّ ﷺ قَدْ أَمَرَهُ بِذَلِكَ
