The two conditions of 'Ibadah
Shaykh ul-Islam Ibn Taymiyyah (رحمه الله) mentions in Majmo' ul-Fataawa:
{...that He may test you which of you is best in deed.} [Surah Al-Mulk 67:2]
Al-Fudayl ibn 'Iyad (رحمه الله) said: "The purest and most accurate deed." The people said: "Oh Abaa 'Ali, what is the purest and most accurate deed?" He said: "If the deed is pure but not accurate it won't be accepted, and if it is accurate but not pure it won't be accepted, until it is both pure and accurate. The meaning of pure is that it is for Allah alone. And the meaning of accurate is that it is according to the Sunnah. That is the actualization of Allah's statement:
{So whoever hopes for the Meeting with his Lord, let him work righteousness and associate none as a partner in the worship of his Lord.} [Surah Al-Kahf 18:110]

قال شيخ الإسلام ابن تيمية رحمه الله
لِيَبْلُوَكُمْ أَيُّكُمْ أَحْسَنُ عَمَلًا ، قَالَ الْفُضَيْل بْنُ عِيَاضٍ : أَخْلَصُهُ وَأَصْوَبُهُ ، قَالُوا : يَا أَبَا عَلِيٍّ مَا أَخْلَصُهُ وَأَصْوَبُهُ ؟ قَالَ : إنَّ الْعَمَلَ إذَا كَانَ خَالِصًا ، وَلَمْ يَكُنْ صَوَابًا ، لَمْ يُقْبَلْ ، وَإِذَا كَانَ صَوَابًا وَلَمْ يَكُنْ خَالِصًا لَمْ يُقْبَلْ ، حَتَّى يَكُونَ خَالِصًا صَوَابًا
وَالْخَالِصُ : أَنْ يَكُونَ لِلَّهِ ، وَالصَّوَابُ : أَنْ يَكُونَ عَلَى السُّنَّةِ، وَذَلِكَ تَحْقِيقُ قَوْله تَعَالَى فَمَنْ كَانَ يَرْجُوا لِقَاءَ رَبِّهِ فَلْيَعْمَلْ عَمَلًا صَالِحًا وَلَا يُشْرِكْ بِعِبَادَةِ رَبِّهِ أَحَدًا انتهى من مجموع الفتاوى 1/ 333
