سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ " غَطُّوا الإِنَاءَ وَأَوْكُوا السِّقَاءَ فَإِنَّ فِي السَّنَةِ لَيْلَةً يَنْزِلُ فِيهَا وَبَاءٌ لاَ يَمُرُّ بِإِنَاءٍ لَيْسَ عَلَيْهِ غِطَاءٌ أَوْ سِقَاءٍ لَيْسَ عَلَيْهِ وِكَاءٌ إِلاَّ نَزَلَ فِيهِ مِنْ ذَلِكَ الْوَبَاءِ ".
Jabir b. 'Abdullah reported Allah's Messenger (ﷺ) as saying:Cover the vessels and tie the waterskin, for there is a night in a year when pestilence descends, and it does not pass an uncovered vessel or an untied waterskin but some of that pestilence descending into it
This hadith is reported on the authority of Laith b. Sa'd with the same chain of transmitters, but with a slight variation in wording (and that is that) he (the Holy Prophet) said:There is a day in a year when descends the pestilence; at the end of the hadith Laith said that the non Arabs save themselves from it in Kanun Awwal (this is the month of December)
