"A man came to the Messenger of Allah ﷺ and said: 'Tell me of an action that is equal to Jihad.' He said: 'I cannot. When the Mujahid goes out, can you enter the Masjid and stand in prayer and never rest, and fast and never break your fast?' He said: 'Who can do that?'"
قَالَ جَاءَ رَجُلٌ إِلَى رَسُولِ اللَّهِ ﷺ فَقَالَ دُلَّنِي عَلَى عَمَلٍ يَعْدِلُ الْجِهَادَ قَالَ لاَ أَجِدُهُ هَلْ تَسْتَطِيعُ إِذَا خَرَجَ الْمُجَاهِدُ تَدْخُلُ مَسْجِدًا فَتَقُومُ لاَ تَفْتُرُ وَتَصُومُ لاَ تُفْطِرُ قَالَ مَنْ يَسْتَطِيعُ ذَلِكَ
