It is narrated from ‘Ubada bin Nusi, who says that Sayyiduna Shaddad bin Aws (may Allah be pleased with him) began to weep. Someone asked him: Why are you weeping? He said: I remembered a hadith that I heard the Messenger of Allah (peace and blessings be upon him) narrate, and that made me weep. I heard him (peace and blessings be upon him) say: I fear for my ummah regarding shirk and hidden desires. I said: O Messenger of Allah! Will your ummah commit shirk after you? He (peace and blessings be upon him) said: Yes, beware! They will not worship the sun, the moon, stones, or idols, but they will show off through their deeds, and the hidden desire is that a servant fasts in the morning, then some desire overcomes him and he breaks his fast.
