Majmu' al-Fatawa - Ibn Taimiya - (7/52)

And in another hadith, also recorded in Sahīh Muslim:

“Whoever strives against them with his hand is a believer; whoever strives against them with his tongue is a believer; and whoever strives against them with his heart is a believer. Beyond that, there is not a mustard seed’s weight of faith.”

Thus, it is clear that if the heart does not hate what Allah hates, it contains none of the faith for which one merits reward.

His words “of faith” refer to this faith—faith in its unqualified sense. That is, beyond these three, there is nothing that constitutes faith, not even a mustard seed’s weight. The meaning is: this is the furthest limit of faith; beyond this, there is no further degree of faith. He does not mean that whoever fails to do this has no faith left at all. Rather, the wording of the hadith indicates only the former meaning.

وَفِي الْحَدِيثِ الْآخَرِ الَّذِي فِي الصَّحِيحِ أَيْضًا - " صَحِيحِ مُسْلِمٍ " -: {فَمَنْ جَاهَدَهُمْ بِيَدِهِ فَهُوَ مُؤْمِنٌ وَمَنْ جَاهَدَهُمْ بِلِسَانِهِ فَهُوَ مُؤْمِنٌ وَمَنْ جَاهَدَهُمْ بِقَلْبِهِ فَهُوَ مُؤْمِنٌ وَلَيْسَ وَرَاءَ ذَلِكَ مِنْ الْإِيمَانِ مِثْقَالُ حَبَّةٍ مِنْ خَرْدَلٍ} . فَعُلِمَ أَنَّ الْقَلْبَ إذَا لَمْ يَكُنْ فِيهِ كَرَاهَةُ مَا يَكْرَهُهُ اللَّهُ؛ لَمْ يَكُنْ فِيهِ مِنْ الْإِيمَانِ الَّذِي يَسْتَحِقُّ بِهِ الثَّوَابَ. وَقَوْلُهُ: {مِنْ الْإِيمَانِ} أَيْ: مِنْ هَذَا الْإِيمَانِ وَهُوَ الْإِيمَانُ الْمُطْلَقُ. أَيْ: لَيْسَ وَرَاءَ هَذِهِ الثَّلَاثِ مَا هُوَ مِنْ الْإِيمَانِ وَلَا قَدْرُ حَبَّةِ خَرْدَلٍ. وَالْمَعْنَى: هَذَا آخِرُ حُدُودِ الْإِيمَانِ، مَا بَقِيَ بَعْدَ هَذَا مِنْ الْإِيمَانِ شَيْءٌ؛ لَيْسَ مُرَادُهُ أَنَّهُ مَنْ لَمْ يَفْعَلْ ذَلِكَ لَمْ يَبْقَ مَعَهُ مِنْ الْإِيمَانِ شَيْءٌ؛ بَلْ لَفْظُ الْحَدِيثِ إنَّمَا يَدُلُّ عَلَى الْمَعْنَى الْأَوَّلِ.
