Mahmood ibn Lubayd reported,“Allaah’s Messenger (ρ) said: The thing I fear for you the most is ash-shirk al-asghar (minor shirk). The companions asked O Messenger of Allaah, what is minor shirk? He replied, ‘Ar-Riyaa’ (showing off), for verily Allaah will say onthe Day of Resurrection when people are receiving their rewards, “Go to thosefor whom you were showing off in the material world and see if you can find any
reward from them."Reported by Ahmad, at-Tabaraanee and al-Bayhaqee in az-Zuhd, See Tayseer al-‘Azeez al-Hameed, p.118.
Mahmood ibn Lubayd also said, “The Prophet (ρ) came out and announced, ‘O
people, beware of secret shirk!’ The people asked, ‘O Messenger of Allaah, what
is secret shirk?’ He replied, ‘When a man gets up to pray and strives to beautify
his prayer because people are looking at him, that is secret shirk.’”Collected by Ibn Khuzaymah.
