MANN and SALWA
And sent down upon you Manna and Salwa (special kind of foods). [Kanz-ul-Iman (Translation of Quran)J (Part 1, Surah Al-Baqarah, Ayah 57)
It was commanded by Sayyiduna Musa to eat Mann and Salwa on daily basis and not to preserve or store for next day at all. But some people bearing weak faith became worried that if Mann and Salwa do not descend some day, then we will be left to starve to death in the plains of this field where no signs of food and water exist. Therefore, they began to secretly preserve some of the food for the following day. As a consequence of disobeying the Nabi, the food they stored rotted and the blessings of Mann and Salwa stopped. That’s why the Holy Rasool said that ‘had the Bani Israel not existed, neither food would get spoiled nor would meat have rotten’. The decay of food and meat rotting started since then. Otherwise, prior to that event, neither food would spoil nor would meat rot. (I’afseer Ruh-ul-Bayan; part 1, Surah Al-Baqarah, Ayah 57)
