Imam al-Sadiq (AS) asked Fuayl, 'Do you sit together and teach the Hadith?' He said, 'Yes, may I be your ransom.' He said, 'These are the assemblies which I love. O Fuayl! Keep our cause alive. May Allah bestow mercy on whoever keeps our cause alive. Whoever remembers us or we are remembered in his presence and sheds a tear as small as a fly's wing, Allah will forgive his sins, even if they are more than the foam of the sea.'
