I heard Anas bin Malik saying: I heard the Messenger of Allah ﷺ say: “Standing guard one night in the cause of Allah is better than a man fasting and praying, among his family, for a thousand years. The year is three hundred and sixty days and a day is like a thousand years.”
سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ حَرْسُ لَيْلَةٍ فِي سَبِيلِ اللَّهِ أَفْضَلُ مِنْ صِيَامِ رَجُلٍ وَقِيَامِهِ فِي أَهْلِهِ أَلْفَ سَنَةٍ السَّنَةُ ثَلاَثُمِائَةٍ وَسِتُّونَ يَوْمًا وَالْيَوْمُ كَأَلْفِ سَنَةٍ
