It is narrated from Imam Mahdi (AJ) who said: There is no kinship between Allah (SWT) and any of God’s servants and every person is rewarded (by God) according to the measure of his/her deeds; whoever denies me (Imam Mahdi (AJ)) is not from us and his/her destiny will be like the destiny of the child (son) of Prophet Noah (AS) [1].
