Sahih al-Bukhari, Hadith 2785 ⓘ
Narrated Abu Huraira: A man came to Allah's Messenger and said, "Instruct me as to such a deed as equals Jihad (in reward)." He replied, "I do not find such a deed." Then he added, "Can you, while the Muslim fighter is in the battle-field, enter your mosque to perform prayers without cease and fast and never break your fast?" The man said, "But who can do that?" Abu- Huraira added, "The Mujahid (i.e. Muslim fighter) is rewarded even for the footsteps of his horse while it wanders bout (for grazing) tied in a long rope."
حَدَّثَنَا إِسْحَاقُ بْنُ مَنْصُورٍ، أَخْبَرَنَا عَفَّانُ، حَدَّثَنَا هَمَّامٌ، حَدَّثَنَا مُحَمَّدُ بْنُ جُحَادَةَ، قَالَ أَخْبَرَنِي أَبُو حَصِينٍ، أَنَّ ذَكْوَانَ، حَدَّثَهُ أَنَّ أَبَا هُرَيْرَةَ ـ رضى الله عنه ـ حَدَّثَهُ قَالَ جَاءَ رَجُلٌ إِلَى رَسُولِ اللَّهِ صلى الله عليه وسلم فَقَالَ دُلَّنِي عَلَى عَمَلٍ يَعْدِلُ الْجِهَادَ. قَالَ " لاَ أَجِدُهُ ـ قَالَ ـ هَلْ تَسْتَطِيعُ إِذَا خَرَجَ الْمُجَاهِدُ أَنْ تَدْخُلَ مَسْجِدَكَ فَتَقُومَ وَلاَ تَفْتُرَ وَتَصُومَ وَلاَ تُفْطِرَ " . قَالَ وَمَنْ يَسْتَطِيعُ ذَلِكَ قَالَ أَبُو هُرَيْرَةَ إِنَّ فَرَسَ الْمُجَاهِدِ لَيَسْتَنُّ فِي طِوَلِهِ فَيُكْتَبُ لَهُ حَسَنَاتٍ.
