Imam al-Sadiq (AS) said, ‘Every single thing has a measure or a weight, except for tears; for one drop of them can extinguish seas of Fire. If an eye is filled with tears, the face will never be burdened with neediness or humiliation; and if it floods with tears then Allah will make it unlawful for the Fire to touch it. Indeed, if a teary man cries for a community, they all receive mercy.’ Mizan al-Hikmah h. 4454
