Is raising the voice in takbir obligatory when there is a fear of riya'?

The questioner : Is raising the voice in takbir obligatory, and if so, what is the ruling for one who fears that people will say this is riya'?

The Shaykh : It is well known among the scholars that raising the voice in takbir is established, except for women. The fact that a person fears riya' is part of Satan’s attempt to frighten him so that he does not perform this sunnah (recommended practice). Satan has ways of entering upon the children of Adam, approaching them from every direction. Therefore, if you know that this is prescribed, do it. If Satan tells you that it is riya', say, "Let it be riya'." If a person were to obey Satan in this matter, then when he entered the state of ihram and raised his voice in the talbiyah, Satan would say to him, "Do not raise your voice in the talbiyah; this is riya'." Would he obey him? No, he would recite the talbiyah with a raised voice. So do not leave off an act out of fear of riya', for that is part of Satan’s deception. And if Allah knows from your intention that you do not seek anything by it but the Face of Allah, then the whispers that come to your heart do not affect your intention.
