The Prophet (peace and blessings be upon him) said to his Companions:
“الشرك فيكم أخفى من دبيب النمل على الصفا ألا أدلك على شيء إذا فعلته أذهب الله عنك صغار ذلك وكباره ، تقول : اللهم إني أعوذ بك أن أشرك بك وأنا أعلم وأستغفرك لما لا أعلم
Shirk among you will be more subtle than the footsteps of an ant, but I will teach you something which, if you do it, both minor and major shirk will be kept away from you. Say:
Allaahumma inni a’oodhu bika an ushrika bika wa ana a’lam wa astaghfiruka lima la a’lam
O Allaah, I seek refuge with You from associating anything with You knowingly, and I seek Your forgiveness for that of which I am unaware.”
