The Ruling on Abandoning Acts of Worship Out of Fear of Showing Off

Question:
Shaykh Salih, meaning some people abandon acts of worship and the regular voluntary prayers (rawatib), saying, "I am afraid of showing off (riya')."

Answer:
This is from Shaytan. A person does not abandon the deed; rather, he performs it and is sincere to Allah the Exalted. This is from Shaytan; he comes to him and says, "Do not pray in congregation. Leave the congregational prayer and pray in your house so that no one sees you. That is more conducive to sincerity." So he obeys Shaytan, prays in his house, and leaves the congregational prayer. He says, "Do not get up at night, do not perform the late-night voluntary prayer (tahajjud) out of fear, do not fast."
Do not perform voluntary acts out of fear of riba (usury or interest). This is from Shaytan. For this reason, some of the Salaf said, "Performing deeds for the sake of people is shirk (associating partners with Allah), and abandoning deeds for the sake of people is shirk." A person performs deeds for Allah, does not look at people, and does not heed the whispers of Shaytan, the devils of mankind and jinn, who say, "We are afraid for you of showing off. Do not display yourself to the people. Do not give charity. Do not do such and such. We are afraid for you of shirk." This is abandonment by Shaytan, and may Allah protect us from it. Yes.
