Sayyiduna Abu Huraira (may Allah be pleased with him) narrates that the Noble Prophet (peace and blessings be upon him) said:“Whoever intends evil against the people of Madinah, Allah Almighty will dissolve him in Hell the way salt dissolves in water. And whoever bears with patience the hardships and difficulties here, I will be a witness for him on the Day of Resurrection (the narrator is in doubt, perhaps these are the words) or I will intercede for him.”
