رحمته صلى الله عليه وسلم
Mahmūd ibn Labīd (may Allah be pleased with him) reported that the Prophet (may Allah's peace and blessings be upon him) said: ''The thing that I fear most for you is minor polytheism.'' When asked what it was, he said: ''Riyā’."
عن محمود بن لبيد -رضي الله عنه- مرفوعاً: "أَخْوَفُ ما أخاف عليكم: الشرك الأصغر، فسئل عنه، فقال: الرياء".
شرح الحديث :
The Prophet (may Allah's peace and blessings be upon him) tells us in this Hadīth that he fears for us, and that the thing he fears for us most is the minor polytheism which is Riyā', which means doing good deeds to show off before people, rather than having a sincere intention to earn Allah's pleasure and reward. There are many and strong motives for Riyā’, so it is possible that a Muslim commits Riyā’ without being aware that he is doing so. Therefore, the Prophet warned Muslims against it, out of perfect compassion for them and concern for their best interests.
