Sheikh Muhammad ibn Salih al-'Uthaymeen mentioned the following in his explanation of Riyadh al-Saliheen: [مهما عملت من الأعمال الصالحة لا تعجب بعملك فعملك قليل بالنسبة لحق الله عليك ] "Whatever kind of good deeds you do, do not become amazed with your own actions, for your deeds are quite small in comparison to Allah's right over you." [Sharh Riyadh al-Saliheen 1/575]
