بسم الله الرحمن الرحيم

In The Name of Allaah, The Most Merciful, The Bestower of Mercy.

Jaabir Bin Abdillaah [may Allaah be pleased with him and his father] said, “I heard Allaah’s Messenger [peace and blessings of Allaah be upon him] saying, ‘Cover the vessels and tie up the water skins, because indeed there is a night during the year when pestilence descends, and it does not pass an uncovered vessel or an untied water-skin, except that some of that pestilence descends into it'”. [Saheeh Muslim 2014]

Imaam Ibnul Qayyim [may Allaah have mercy upon him] said, “This is one of those affairs which the sciences of doctors and their knowledge cannot reach. It is known by way of experience to those who know it amongst the people of sound intelligence”. [At-Tibb An-Nabawiy. page 173]
